+Interface for registering and calling firmware-specific operations for ARM.
+----
+Written by Tomasz Figa <t.figa@samsung.com>
+
+Some boards are running with secure firmware running in TrustZone secure
+world, which changes the way some things have to be initialized. This makes
+a need to provide an interface for such platforms to specify available firmware
+operations and call them when needed.
+
+Firmware operations can be specified using struct firmware_ops
+
+	struct firmware_ops {
+		/*
+		* Enters CPU idle mode
+		*/
+		int (*do_idle)(void);
+		/*
+		* Sets boot address of specified physical CPU
+		*/
+		int (*set_cpu_boot_addr)(int cpu, unsigned long boot_addr);
+		/*
+		* Boots specified physical CPU
+		*/
+		int (*cpu_boot)(int cpu);
+		/*
+		* Initializes L2 cache
+		*/
+		int (*l2x0_init)(void);
+	};
+
+and then registered with register_firmware_ops function
+
+	void register_firmware_ops(const struct firmware_ops *ops)
+
+the ops pointer must be non-NULL.
+
+There is a default, empty set of operations provided, so there is no need to
+set anything if platform does not require firmware operations.
+
+To call a firmware operation, a helper macro is provided
+
+	#define call_firmware_op(op, ...)				\
+		((firmware_ops->op) ? firmware_ops->op(__VA_ARGS__) : (-ENOSYS))
+
+the macro checks if the operation is provided and calls it or otherwise returns
+-ENOSYS to signal that given operation is not available (for example, to allow
+fallback to legacy operation).
+
+Example of registering firmware operations:
+
+	/* board file */
+
+	static int platformX_do_idle(void)
+	{
+		/* tell platformX firmware to enter idle */
+		return 0;
+	}
+
+	static int platformX_cpu_boot(int i)
+	{
+		/* tell platformX firmware to boot CPU i */
+		return 0;
+	}
+
+	static const struct firmware_ops platformX_firmware_ops = {
+		.do_idle        = exynos_do_idle,
+		.cpu_boot       = exynos_cpu_boot,
+		/* other operations not available on platformX */
+	};
+
+	/* init_early callback of machine descriptor */
+	static void __init board_init_early(void)
+	{
+		register_firmware_ops(&platformX_firmware_ops);
+	}
+
+Example of using a firmware operation:
+
+	/* some platform code, e.g. SMP initialization */
+
+	__raw_writel(virt_to_phys(exynos4_secondary_startup),
+		CPU1_BOOT_REG);
+
+	/* Call Exynos specific smc call */
+	if (call_firmware_op(cpu_boot, cpu) == -ENOSYS)
+		cpu_boot_legacy(...); /* Try legacy way */
+
+	gic_raise_softirq(cpumask_of(cpu), 1);

+* Samsung Exynos System MMU
+
+Samsung's Exynos architecture includes System MMU that enables scattered
+physical chunks to be visible as a contiguous region to DMA-capabile peripheral
+devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
+
+System MMU is a sort of IOMMU and support identical translation table format to
+ARMv7 translation tables with minimum set of page properties including access
+permissions, shareability and security protection. In addition System MMU has
+another capabilities like L2 TLB or block-fetch buffers to minimize translation
+latency
+
+Each System MMU is included in the H/W block of a peripheral device. Thus, it is
+important to specify that a System MMU is dedicated to which peripheral device
+before using System MMU. System initialization must specify the relationships
+between a System MMU and a peripheral device that owns the System MMU.
+
+Some device drivers may control several peripheral devices with a single device
+descriptor like MFC. Since handling a System MMU with IOMMU API requires a
+device descriptor that needs the System MMU, it is best to combine the System
+MMUs of the peripheral devices and control them with a single System MMU device
+descriptor. If it is unable to combine them into a single device descriptor,
+they can be linked with each other by the means of device.parent relationship.
+
+Required properties:
+- compatible: Should be "samsung,exynos-sysmmu".
+- reg: Tuples of base address and size of System MMU registers. The number of
+       tuples can be more than one if two or more System MMUs are controlled
+       by a single device descriptor.
+- interrupt-parent: The phandle of the interrupt controller of System MMU
+- interrupts: Tuples of numbers that indicates the interrupt source. The
+              number of elements in the tuple is dependent upon
+             'interrupt-parent' property. The number of tuples in this property
+             must be the same with 'reg' property.
+
+Optional properties:
+- mmuname: Strings of the name of System MMU for debugging purpose. The number
+          of strings must be the same with the number of tuples in 'reg'
+          property.
+- mmu-master: phandle to the device node that owns System MMU. Only the device
+          that is specified whith this property can control System MMU with
+          IOMMU API.
+
+Examples:
+
+MFC has 2 System MMUs for each port that MFC is attached. Thus it seems natural
+to define 2 System MMUs for each port of the MFC:
+
+	sysmmu-mfc-l {
+		mmuname = "mfc_l";
+		reg = <0x11210000 0x1000>;
+		compatible = "samsung,exynos-sysmmu";
+		interrupt-parent = <&combiner>;
+		interrupts = <8 5>;
+		mmu-master = <&mfc>;
+	};
+
+	sysmmu-mfc-r {
+		mmuname = "mfc_r";
+		reg = <0x11200000 0x1000>;
+		compatible = "samsung,exynos-sysmmu";
+		interrupt-parent = <&combiner>;
+		interrupts = <6 2>;
+		mmu-master = <&mfc>;
+	};
+
+Actually, MFC device driver requires sub-devices that represents each port and
+above 'mmu-master' properties of sysmmu-mfc-l and sysmmu-mfc-r have the phandles
+to those sub-devices.
+
+However, it is also a good idea that treats the above System MMUs as one System
+MMU because those System MMUs are actually required by the MFC device:
+
+	sysmmu-mfc {
+		mmuname = "mfc_l", "mfc_r";
+		reg = <0x11210000 0x1000
+		       0x11200000 0x1000>;
+		compatible = "samsung,exynos-sysmmu";
+		interrupt-parent = <&combiner>;
+		interrupts = <8 5
+			      6 2>;
+		mmu-master = <&mfc>;
+	};
+
+If System MMU of MFC is defined like the above, the number of elements and the
+order of list in 'mmuname', 'reg' and 'interrupts' must be the same.

+* Generic DMA Controller and DMA request bindings
+
+Generic binding to provide a way for a driver using DMA Engine to retrieve the

+
+Optional properties:
+- dma-channels: 	Number of DMA channels supported by the controller.
+- dma-requests: 	Number of DMA requests signals supported by the
+			controller.
+
+Example:
+
+	dma: dma@48000000 {
+		compatible = "ti,omap-sdma";
+		reg = <0x48000000 0x1000>;

+		#dma-cells = <1>;
+		dma-channels = <32>;
+		dma-requests = <127>;
+	};
+
+
+* DMA client
+
+Client drivers should specify the DMA property using a phandle to the controller
+followed by DMA controller specific data.
+
+Required property:
+- dmas:			List of one or more DMA specifiers, each consisting of
+			- A phandle pointing to DMA controller node
+			- A number of integer cells, as determined by the
+			  #dma-cells property in the node referenced by phandle
+			  containing DMA controller specific information. This
+			  typically contains a DMA request line number or a
+			  channel number, but can contain any data that is used
+			  required for configuring a channel.
+- dma-names: 		Contains one identifier string for each DMA specifier in
+			the dmas property. The specific strings that can be used
+			are defined in the binding of the DMA client device.
+			Multiple DMA specifiers can be used to represent
+			alternatives and in this case the dma-names for those
+			DMA specifiers must be identical (see examples).
+
+Examples:
+
+1. A device with one DMA read channel, one DMA write channel:
+

+		...
+		dmas = <&dma 2		/* read channel */
+			&dma 3>;	/* write channel */
+		dma-names = "rx", "tx";

+
+2. A single read-write channel with three alternative DMA controllers:
+
+	dmas = <&dma1 5
+		&dma2 7
+		&dma3 2>;
+	dma-names = "rx-tx", "rx-tx", "rx-tx";
+
+3. A device with three channels, one of which has two alternatives:

+EXYNOS EMULATION MODE
+========================
+
+Copyright (C) 2012 Samsung Electronics
+
+Written by Jonghwa Lee <jonghwa3.lee@samsung.com>
+
+Description
+-----------
+
+Exynos 4x12 (4212, 4412) and 5 series provide emulation mode for thermal management unit.
+Thermal emulation mode supports software debug for TMU's operation. User can set temperature
+manually with software code and TMU will read current temperature from user value not from
+sensor's value.
+
+Enabling CONFIG_EXYNOS_THERMAL_EMUL option will make this support in available.
+When it's enabled, sysfs node will be created under
+/sys/bus/platform/devices/'exynos device name'/ with name of 'emulation'.
+
+The sysfs node, 'emulation', will contain value 0 for the initial state. When you input any
+temperature you want to update to sysfs node, it automatically enable emulation mode and
+current temperature will be changed into it.
+(Exynos also supports user changable delay time which would be used to delay of
+ changing temperature. However, this node only uses same delay of real sensing time, 938us.)
+
+Exynos emulation mode requires synchronous of value changing and enabling. It means when you
+want to update the any value of delay or next temperature, then you have to enable emulation
+mode at the same time. (Or you have to keep the mode enabling.) If you don't, it fails to
+change the value to updated one and just use last succeessful value repeatedly. That's why
+this node gives users the right to change termerpature only. Just one interface makes it more
+simply to use.
+
+Disabling emulation mode only requires writing value 0 to sysfs node.

-4. Overview and features
-========================
-This driver supports the video interface of the devices mounting the ET61X151
-or ET61X251 PC Camera Controllers.
-
-It's worth to note that Etoms Electronics has never collaborated with the
-author during the development of this project; despite several requests,
-Etoms Electronics also refused to release enough detailed specifications of
-the video compression engine.
-
-The driver relies on the Video4Linux2 and USB core modules. It has been
-designed to run properly on SMP systems as well.
-
-The latest version of the ET61X[12]51 driver can be found at the following URL:
-http://www.linux-projects.org/
-
-Some of the features of the driver are:
-
-- full compliance with the Video4Linux2 API (see also "Notes for V4L2
-  application developers" paragraph);
-- available mmap or read/poll methods for video streaming through isochronous
-  data transfers;
-- automatic detection of image sensor;
-- support for any window resolutions and optional panning within the maximum
-  pixel area of image sensor;
-- image downscaling with arbitrary scaling factors from 1 and 2 in both
-  directions (see "Notes for V4L2 application developers" paragraph);
-- two different video formats for uncompressed or compressed data in low or
-  high compression quality (see also "Notes for V4L2 application developers"
-  paragraph);
-- full support for the capabilities of every possible image sensors that can
-  be connected to the ET61X[12]51 bridges, including, for instance, red, green,
-  blue and global gain adjustments and exposure control (see "Supported
-  devices" paragraph for details);
-- use of default color settings for sunlight conditions;
-- dynamic I/O interface for both ET61X[12]51 and image sensor control (see
-  "Optional device control through 'sysfs'" paragraph);
-- dynamic driver control thanks to various module parameters (see "Module
-  parameters" paragraph);
-- up to 64 cameras can be handled at the same time; they can be connected and
-  disconnected from the host many times without turning off the computer, if
-  the system supports hotplugging;
-- no known bugs.
-
-
-5. Module dependencies
-======================
-For it to work properly, the driver needs kernel support for Video4Linux and
-USB.
-
-The following options of the kernel configuration file must be enabled and
-corresponding modules must be compiled:
-
-	# Multimedia devices
-	#
-	CONFIG_VIDEO_DEV=m
-
-To enable advanced debugging functionality on the device through /sysfs:
-
-	# Multimedia devices
-	#
-	CONFIG_VIDEO_ADV_DEBUG=y
-
-	# USB support
-	#
-	CONFIG_USB=m
-
-In addition, depending on the hardware being used, the modules below are
-necessary:
-
-	# USB Host Controller Drivers
-	#
-	CONFIG_USB_EHCI_HCD=m
-	CONFIG_USB_UHCI_HCD=m
-	CONFIG_USB_OHCI_HCD=m
-
-And finally:
-
-	# USB Multimedia devices
-	#
-	CONFIG_USB_ET61X251=m
-
-
-6. Module loading
-=================
-To use the driver, it is necessary to load the "et61x251" module into memory
-after every other module required: "videodev", "v4l2_common", "compat_ioctl32",
-"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
-"uhci-hcd" or "ohci-hcd".
-
-Loading can be done as shown below:
-
-	[root@localhost home]# modprobe et61x251
-
-At this point the devices should be recognized. You can invoke "dmesg" to
-analyze kernel messages and verify that the loading process has gone well:
-
-	[user@localhost home]$ dmesg
-
-
-7. Module parameters
-====================
-Module parameters are listed below:
--------------------------------------------------------------------------------
-Name:           video_nr
-Type:           short array (min = 0, max = 64)
-Syntax:         <-1|n[,...]>
-Description:    Specify V4L2 minor mode number:
-		-1 = use next available
-		 n = use minor number n
-		You can specify up to 64 cameras this way.
-		For example:
-		video_nr=-1,2,-1 would assign minor number 2 to the second
-		registered camera and use auto for the first one and for every
-		other camera.
-Default:        -1
--------------------------------------------------------------------------------
-Name:           force_munmap
-Type:           bool array (min = 0, max = 64)
-Syntax:         <0|1[,...]>
-Description:    Force the application to unmap previously mapped buffer memory
-		before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
-		all the applications support this feature. This parameter is
-		specific for each detected camera.
-		0 = do not force memory unmapping
-		1 = force memory unmapping (save memory)
-Default:        0
--------------------------------------------------------------------------------
-Name:           frame_timeout
-Type:           uint array (min = 0, max = 64)
-Syntax:         <n[,...]>
-Description:    Timeout for a video frame in seconds. This parameter is
-		specific for each detected camera. This parameter can be
-		changed at runtime thanks to the /sys filesystem interface.
-Default:        2
--------------------------------------------------------------------------------
-Name:           debug
-Type:           ushort
-Syntax:         <n>
-Description:    Debugging information level, from 0 to 3:
-		0 = none (use carefully)
-		1 = critical errors
-		2 = significant information
-		3 = more verbose messages
-		Level 3 is useful for testing only, when only one device
-		is used at the same time. It also shows some more information
-		about the hardware being detected. This module parameter can be
-		changed at runtime thanks to the /sys filesystem interface.
-Default:        2
--------------------------------------------------------------------------------
-
-
-8. Optional device control through "sysfs"
-==========================================
-If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
-it is possible to read and write both the ET61X[12]51 and the image sensor
-registers by using the "sysfs" filesystem interface.
-
-There are four files in the /sys/class/video4linux/videoX directory for each
-registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files
-control the ET61X[12]51 bridge, while the other two control the sensor chip.
-"reg" and "i2c_reg" hold the values of the current register index where the
-following reading/writing operations are addressed at through "val" and
-"i2c_val". Their use is not intended for end-users, unless you know what you
-are doing. Remember that you must be logged in as root before writing to them.
-
-As an example, suppose we were to want to read the value contained in the
-register number 1 of the sensor register table - which is usually the product
-identifier - of the camera registered as "/dev/video0":
-
-	[root@localhost #] cd /sys/class/video4linux/video0
-	[root@localhost #] echo 1 > i2c_reg
-	[root@localhost #] cat i2c_val
-
-Note that if the sensor registers cannot be read, "cat" will fail.
-To avoid race conditions, all the I/O accesses to the files are serialized.
-
-
-9. Supported devices
-====================
-None of the names of the companies as well as their products will be mentioned
-here. They have never collaborated with the author, so no advertising.
-
-From the point of view of a driver, what unambiguously identify a device are
-its vendor and product USB identifiers. Below is a list of known identifiers of
-devices mounting the ET61X[12]51 PC camera controllers:

-10. Notes for V4L2 application developers
-=========================================
-This driver follows the V4L2 API specifications. In particular, it enforces two
-rules:
-
-- exactly one I/O method, either "mmap" or "read", is associated with each
-file descriptor. Once it is selected, the application must close and reopen the
-device to switch to the other I/O method;
-
-- although it is not mandatory, previously mapped buffer memory should always
-be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
-The same number of buffers as before will be allocated again to match the size
-of the new video frames, so you have to map the buffers again before any I/O
-attempts on them.
-
-Consistently with the hardware limits, this driver also supports image
-downscaling with arbitrary scaling factors from 1 and 2 in both directions.
-However, the V4L2 API specifications don't correctly define how the scaling
-factor can be chosen arbitrarily by the "negotiation" of the "source" and
-"target" rectangles. To work around this flaw, we have added the convention
-that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the
-scaling factor is restored to 1.
-
-This driver supports two different video formats: the first one is the "8-bit
-Sequential Bayer" format and can be used to obtain uncompressed video data
-from the device through the current I/O method, while the second one provides
-"raw" compressed video data (without frame headers not related to the
-compressed data). The current compression quality may vary from 0 to 1 and can
-be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP
-V4L2 ioctl's.

-README for Linux device driver for the IBM "C-It" USB video camera
-
-INTRODUCTION:
-
-This driver does not use all features known to exist in
-the IBM camera. However most of needed features work well.
-
-This driver was developed using logs of observed USB traffic
-which was produced by standard Windows driver (c-it98.sys).
-I did not have data sheets from Xirlink.
-
-Video formats:
-      128x96  [model 1]
-      176x144
-      320x240 [model 2]
-      352x240 [model 2]
-      352x288
-Frame rate: 3 - 30 frames per second (FPS)
-External interface: USB
-Internal interface: Video For Linux (V4L)
-Supported controls:
-- by V4L: Contrast,  Brightness, Color, Hue
-- by driver options: frame rate, lighting conditions, video format,
-		     default picture settings, sharpness.
-
-SUPPORTED CAMERAS:
-
-Xirlink "C-It" camera, also known as "IBM PC Camera".
-The device uses proprietary ASIC (and compression method);
-it is manufactured by Xirlink. See http://xirlinkwebcam.sourceforge.net, 
-http://www.ibmpccamera.com, or http://www.c-itnow.com/ for details and pictures.
-
-This very chipset ("X Chip", as marked at the factory)
-is used in several other cameras, and they are supported
-as well:
-
-- IBM NetCamera
-- Veo Stingray
-
-The Linux driver was developed with camera with following
-model number (or FCC ID): KSX-XVP510. This camera has three
-interfaces, each with one endpoint (control, iso, iso). This
-type of cameras is referred to as "model 1". These cameras are
-no longer manufactured.
-
-Xirlink now manufactures new cameras which are somewhat different.
-In particular, following models [FCC ID] belong to that category:
-
-XVP300 [KSX-X9903]
-XVP600 [KSX-X9902]
-XVP610 [KSX-X9902]
-
-(see http://www.xirlink.com/ibmpccamera/ for updates, they refer
-to these new cameras by Windows driver dated 12-27-99, v3005 BETA)
-These cameras have two interfaces, one endpoint in each (iso, bulk).
-Such type of cameras is referred to as "model 2". They are supported
-(with exception of 352x288 native mode).
-
-Some IBM NetCameras (Model 4) are made to generate only compressed
-video streams. This is great for performance, but unfortunately
-nobody knows how to decompress the stream :-( Therefore, these
-cameras are *unsupported* and if you try to use one of those, all
-you get is random colored horizontal streaks, not the image!
-If you have one of those cameras, you probably should return it
-to the store and get something that is supported.
-
-Tell me more about all that "model" business
---------------------------------------------
-
-I just invented model numbers to uniquely identify flavors of the
-hardware/firmware that were sold. It was very confusing to use
-brand names or some other internal numbering schemes. So I found
-by experimentation that all Xirlink chipsets fall into four big
-classes, and I called them "models". Each model is programmed in
-its own way, and each model sends back the video in its own way.
-
-Quirks of Model 2 cameras:
--------------------------
-
-Model 2 does not have hardware contrast control. Corresponding V4L
-control is implemented in software, which is not very nice to your
-CPU, but at least it works.
-
-This driver provides 352x288 mode by switching the camera into
-quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting
-this mode to 10 frames per second or less, in ideal conditions on
-the bus (USB is shared, after all). The frame rate
-has to be programmed very conservatively. Additional concern is that
-frame rate depends on brightness setting; therefore the picture can
-be good at one brightness and broken at another! I did not want to fix
-the frame rate at slowest setting, but I had to move it pretty much down
-the scale (so that framerate option barely matters). I also noticed that
-camera after first powering up produces frames slightly faster than during
-consecutive uses. All this means that if you use 352x288 (which is
-default), be warned - you may encounter broken picture on first connect;
-try to adjust brightness - brighter image is slower, so USB will be able
-to send all data. However if you regularly use Model 2 cameras you may
-prefer 176x144 which makes perfectly good I420, with no scaling and
-lesser demands on USB (300 Kbits per second, or 26 frames per second).
-
-Another strange effect of 352x288 mode is the fine vertical grid visible
-on some colored surfaces. I am sure it is caused by me not understanding
-what the camera is trying to say. Blame trade secrets for that.
-
-The camera that I had also has a hardware quirk: if disconnected,
-it needs few minutes to "relax" before it can be plugged in again
-(poorly designed USB processor reset circuit?)
-
-[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't
-observed this particular flaw in it.]
-
-Model 2 camera can be programmed for very high sensitivity (even starlight
-may be enough), this makes it convenient for tinkering with. The driver
-code has enough comments to help a programmer to tweak the camera
-as s/he feels necessary.
-
-WHAT YOU NEED:
-
-- A supported IBM PC (C-it) camera (model 1 or 2)
-
-- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work)
-
-- A Video4Linux compatible frame grabber program such as xawtv.
-
-HOW TO COMPILE THE DRIVER:
-
-You need to compile the driver only if you are a developer
-or if you want to make changes to the code. Most distributions
-precompile all modules, so you can go directly to the next
-section "HOW TO USE THE DRIVER".
-
-The ibmcam driver uses usbvideo helper library (module),
-so if you are studying the ibmcam code you will be led there.
-
-The driver itself consists of only one file in usb/ directory:
-ibmcam.c. This file is included into the Linux kernel build
-process if you configure the kernel for CONFIG_USB_IBMCAM.
-Run "make xconfig" and in USB section you will find the IBM
-camera driver. Select it, save the configuration and recompile.
-
-HOW TO USE THE DRIVER:
-
-I recommend to compile driver as a module. This gives you an
-easier access to its configuration. The camera has many more
-settings than V4L can operate, so some settings are done using
-module options.
-
-To begin with, on most modern Linux distributions the driver
-will be automatically loaded whenever you plug the supported
-camera in. Therefore, you don't need to do anything. However
-if you want to experiment with some module parameters then
-you can load and unload the driver manually, with camera
-plugged in or unplugged.
-
-Typically module is installed with command 'modprobe', like this:
-
-# modprobe ibmcam framerate=1
-
-Alternatively you can use 'insmod' in similar fashion:
-
-# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1
-
-Module can be inserted with camera connected or disconnected.
-
-The driver can have options, though some defaults are provided.
-
-Driver options: (* indicates that option is model-dependent)

-
-debug           You don't need this option unless you are a developer.
-		If you are a developer then you will see in the code
-		what values do what. 0=off.
-
-flags           This is a bit mask, and you can combine any number of
-		bits to produce what you want. Usually you don't want
-		any of extra features this option provides:
-
-		FLAGS_RETRY_VIDIOCSYNC  1  This bit allows to retry failed
-					   VIDIOCSYNC ioctls without failing.
-					   Will work with xawtv, will not
-					   with xrealproducer. Default is
-					   not set.
-		FLAGS_MONOCHROME        2  Activates monochrome (b/w) mode.
-		FLAGS_DISPLAY_HINTS     4  Shows colored pixels which have
-					   magic meaning to developers.
-		FLAGS_OVERLAY_STATS     8  Shows tiny numbers on screen,
-					   useful only for debugging.
-		FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers.
-		FLAGS_SEPARATE_FRAMES   32 Shows each frame separately, as
-					   it was received from the camera.
-					   Default (not set) is to mix the
-					   preceding frame in to compensate
-					   for occasional loss of Isoc data
-					   on high frame rates.
-		FLAGS_CLEAN_FRAMES      64 Forces "cleanup" of each frame
-					   prior to use; relevant only if
-					   FLAGS_SEPARATE_FRAMES is set.
-					   Default is not to clean frames,
-					   this is a little faster but may
-					   produce flicker if frame rate is
-					   too high and Isoc data gets lost.
-		FLAGS_NO_DECODING      128 This flag turns the video stream
-					   decoder off, and dumps the raw
-					   Isoc data from the camera into
-					   the reading process. Useful to
-					   developers, but not to users.
-
-framerate       This setting controls frame rate of the camera. This is
-		an approximate setting (in terms of "worst" ... "best")
-		because camera changes frame rate depending on amount
-		of light available. Setting 0 is slowest, 6 is fastest.
-		Beware - fast settings are very demanding and may not
-		work well with all video sizes. Be conservative.
-
-hue_correction  This highly optional setting allows to adjust the
-		hue of the image in a way slightly different from
-		what usual "hue" control does. Both controls affect
-		YUV colorspace: regular "hue" control adjusts only
-		U component, and this "hue_correction" option similarly
-		adjusts only V component. However usually it is enough
-		to tweak only U or V to compensate for colored light or
-		color temperature; this option simply allows more
-		complicated correction when and if it is necessary.
-
-init_brightness These settings specify _initial_ values which will be
-init_contrast   used to set up the camera. If your V4L application has
-init_color      its own controls to adjust the picture then these
-init_hue        controls will be used too. These options allow you to
-		preconfigure the camera when it gets connected, before
-		any V4L application connects to it. Good for webcams.
-
-init_model2_rg  These initial settings alter color balance of the
-init_model2_rg2 camera on hardware level. All four settings may be used
-init_model2_sat to tune the camera to specific lighting conditions. These
-init_model2_yb  settings only apply to Model 2 cameras.
-
-lighting        This option selects one of three hardware-defined
-		photosensitivity settings of the camera. 0=bright light,
-		1=Medium (default), 2=Low light. This setting affects
-		frame rate: the dimmer the lighting the lower the frame
-		rate (because longer exposition time is needed). The
-		Model 2 cameras allow values more than 2 for this option,
-		thus enabling extremely high sensitivity at cost of frame
-		rate, color saturation and imaging sensor noise.
-
-sharpness       This option controls smoothing (noise reduction)
-		made by camera. Setting 0 is most smooth, setting 6
-		is most sharp. Be aware that CMOS sensor used in the
-		camera is pretty noisy, so if you choose 6 you will
-		be greeted with "snowy" image. Default is 4. Model 2

-
-size            This setting chooses one of several image sizes that are
-		supported by this driver. Cameras may support more, but
-		it's difficult to reverse-engineer all formats.
-		Following video sizes are supported:
-
-		size=0     128x96  (Model 1 only)
-		size=1     160x120
-		size=2     176x144
-		size=3     320x240 (Model 2 only)

-		size=5     352x288
-		size=6     640x480 (Model 3 only)
-
-		The 352x288 is the native size of the Model 1 sensor
-		array, so it's the best resolution the camera can
-		yield. The best resolution of Model 2 is 176x144, and
-		larger images are produced by stretching the bitmap.
-		Model 3 has sensor with 640x480 grid, and it works too,
-		but the frame rate will be exceptionally low (1-2 FPS);
-		it may be still OK for some applications, like security.
-		Choose the image size you need. The smaller image can
-		support faster frame rate. Default is 352x288.

-WHAT NEEDS TO BE DONE:
-
-- The button on the camera is not used. I don't know how to get to it.
-  I know now how to read button on Model 2, but what to do with it?
-
-- Camera reports its status back to the driver; however I don't know
-  what returned data means. If camera fails at some initialization
-  stage then something should be done, and I don't do that because
-  I don't even know that some command failed. This is mostly Model 1
-  concern because Model 2 uses different commands which do not return
-  status (and seem to complete successfully every time).
-
-- Some flavors of Model 4 NetCameras produce only compressed video
-  streams, and I don't know how to decode them.

-Readme for Linux device driver for the OmniVision OV511 USB to camera bridge IC
--------------------------------------------------------------------------------
-
-Author: Mark McClelland
-Homepage: http://alpha.dyndns.org/ov511
-
-INTRODUCTION:
-
-This is a driver for the OV511, a USB-only chip used in many "webcam" devices.
-Any camera using the OV511/OV511+ and the OV6620/OV7610/20/20AE should work.
-Video capture devices that use the Philips SAA7111A decoder also work. It
-supports streaming and capture of color or monochrome video via the Video4Linux
-API. Most V4L apps are compatible with it. Most resolutions with a width and
-height that are a multiple of 8 are supported.
-
-If you need more information, please visit the OV511 homepage at the above URL.
-
-WHAT YOU NEED:
-
-- If you want to help with the development, get the chip's specification docs at
-  http://www.ovt.com/omniusbp.html
-
-- A Video4Linux compatible frame grabber program (I recommend vidcat and xawtv)
-    vidcat is part of the w3cam package:  http://mpx.freeshell.net/
-    xawtv is available at:  http://linux.bytesex.org/xawtv/
-
-HOW TO USE IT:
-
-Note: These are simplified instructions. For complete instructions see:
-	http://alpha.dyndns.org/ov511/install.html
-
-You must have first compiled USB support, support for your specific USB host
-controller (UHCI or OHCI), and Video4Linux support for your kernel (I recommend
-making them modules.) Make sure "Enforce bandwidth allocation" is NOT enabled.
-
-Next, (as root):
-
-	modprobe usbcore
-	modprobe usb-uhci  <OR>  modprobe usb-ohci
-	modprobe videodev
-	modprobe ov511
-
-If it is not already there (it usually is), create the video device:
-
-	mknod /dev/video0 c 81 0
-
-Optionally, symlink /dev/video to /dev/video0
-
-You will have to set permissions on this device to allow you to read/write
-from it:
-
-	chmod 666 /dev/video
-	chmod 666 /dev/video0 (if necessary)
-
-Now you are ready to run a video app! Both vidcat and xawtv work well for me
-at 640x480.
-
-[Using vidcat:]
-
-	vidcat -s 640x480 -p c > test.jpg
-	xview test.jpg
-
-[Using xawtv:]
-
-From the main xawtv directory:
-
-	make clean
-	./configure
-	make
-	make install
-
-Now you should be able to run xawtv. Right click for the options dialog.
-
-MODULE PARAMETERS:
-
-  You can set these with:  insmod ov511 NAME=VALUE
-  There is currently no way to set these on a per-camera basis.
-
-  NAME: autobright
-  TYPE: integer (Boolean)
-  DEFAULT: 1
-  DESC: Brightness is normally under automatic control and can't be set
-	manually by the video app. Set to 0 for manual control.
-
-  NAME: autogain
-  TYPE: integer (Boolean)
-  DEFAULT: 1
-  DESC: Auto Gain Control enable. This feature is not yet implemented.
-
-  NAME: autoexp
-  TYPE: integer (Boolean)
-  DEFAULT: 1
-  DESC: Auto Exposure Control enable. This feature is not yet implemented.
-
-  NAME: debug
-  TYPE: integer (0-6)
-  DEFAULT: 3
-  DESC: Sets the threshold for printing debug messages. The higher the value,
-	the more is printed. The levels are cumulative, and are as follows:
-	  0=no debug messages
-	  1=init/detection/unload and other significant messages
-	  2=some warning messages
-	  3=config/control function calls
-	  4=most function calls and data parsing messages
-	  5=highly repetitive mesgs
-
-  NAME: snapshot
-  TYPE: integer (Boolean)
-  DEFAULT: 0
-  DESC: Set to 1 to enable snapshot mode. read()/VIDIOCSYNC will block until
-	the snapshot button is pressed. Note: enabling this mode disables
-	/proc/video/ov511/<minor#>/button
-
-  NAME: cams
-  TYPE: integer (1-4 for OV511, 1-31 for OV511+)
-  DEFAULT: 1
-  DESC: Number of cameras allowed to stream simultaneously on a single bus.
-	Values higher than 1 reduce the data rate of each camera, allowing two
-	or more to be used at once. If you have a complicated setup involving
-	both OV511 and OV511+ cameras, trial-and-error may be necessary for
-	finding the optimum setting.
-
-  NAME: compress
-  TYPE: integer (Boolean)
-  DEFAULT: 0
-  DESC: Set this to 1 to turn on the camera's compression engine. This can
-	potentially increase the frame rate at the expense of quality, if you
-	have a fast CPU. You must load the proper compression module for your
-	camera before starting your application (ov511_decomp or ov518_decomp).
-
-  NAME: testpat
-  TYPE: integer (Boolean)
-  DEFAULT: 0
-  DESC: This configures the camera's sensor to transmit a colored test-pattern
-	instead of an image. This does not work correctly yet.
-
-  NAME: dumppix
-  TYPE: integer (0-2)
-  DEFAULT: 0
-  DESC: Dumps raw pixel data and skips post-processing and format conversion.
-	It is for debugging purposes only. Options are:
-		0: Disable (default)
-		1: Dump raw data from camera, excluding headers and trailers
-		2: Dumps data exactly as received from camera
-
-  NAME: led
-  TYPE: integer (0-2)
-  DEFAULT: 1 (Always on)
-  DESC: Controls whether the LED (the little light) on the front of the camera
-	is always off (0), always on (1), or only on when driver is open (2).
-	This is not supported with the OV511, and might only work with certain
-	cameras (ones that actually have the LED wired to the control pin, and
-	not just hard-wired to be on all the time).
-
-  NAME: dump_bridge
-  TYPE: integer (Boolean)
-  DEFAULT: 0
-  DESC: Dumps the bridge (OV511[+] or OV518[+]) register values to the system
-	log. Only useful for serious debugging/development purposes.
-
-  NAME: dump_sensor
-  TYPE: integer (Boolean)
-  DEFAULT: 0
-  DESC: Dumps the sensor register values to the system log. Only useful for
-	serious debugging/development purposes.
-
-  NAME: printph
-  TYPE: integer (Boolean)
-  DEFAULT: 0
-  DESC: Setting this to 1 will dump the first 12 bytes of each isoc frame. This
-	is only useful if you are trying to debug problems with the isoc data
-	stream (i.e.: camera initializes, but vidcat hangs until Ctrl-C). Be
-	warned that this dumps a large number of messages to your kernel log.
-
-  NAME: phy, phuv, pvy, pvuv, qhy, qhuv, qvy, qvuv
-  TYPE: integer (0-63 for phy and phuv, 0-255 for rest)
-  DEFAULT: OV511 default values
-  DESC: These are registers 70h - 77h of the OV511, which control the
-	prediction ranges and quantization thresholds of the compressor, for
-	the Y and UV channels in the horizontal and vertical directions. See
-	the OV511 or OV511+ data sheet for more detailed descriptions. These
-	normally do not need to be changed.
-
-  NAME: lightfreq
-  TYPE: integer (0, 50, or 60)
-  DEFAULT: 0 (use sensor default)
-  DESC: Sets the sensor to match your lighting frequency. This can reduce the
-	appearance of "banding", i.e. horizontal lines or waves of light and
-	dark that are often caused by artificial lighting. Valid values are:
-		0 - Use default (depends on sensor, most likely 60 Hz)
-		50 - For European and Asian 50 Hz power
-		60 - For American 60 Hz power
-
-  NAME: bandingfilter
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (off)
-  DESC: Enables the sensor´s banding filter exposure algorithm. This reduces
-	or stabilizes the "banding" caused by some artificial light sources
-	(especially fluorescent). You might have to set lightfreq correctly for
-	this to work right. As an added bonus, this sometimes makes it
-	possible to capture your monitor´s output.
-
-  NAME: fastset
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (off)
-  DESC: Allows picture settings (brightness, contrast, color, and hue) to take
-	effect immediately, even in the middle of a frame. This reduces the
-	time to change settings, but can ruin frames during the change. Only
-	affects OmniVision sensors.
-
-  NAME: force_palette
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (off)
-  DESC: Forces the palette (color format) to a specific value. If an
-	application requests a different palette, it will be rejected, thereby
-	forcing it to try others until it succeeds. This is useful for forcing
-	greyscale mode with a color camera, for example. Supported modes are:
-		0                           (Allows all the following formats)
-		1   VIDEO_PALETTE_GREY      (Linear greyscale)
-		10  VIDEO_PALETTE_YUV420    (YUV 4:2:0 Planar)
-		15  VIDEO_PALETTE_YUV420P   (YUV 4:2:0 Planar, same as 10)
-
-  NAME: backlight
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (off)
-  DESC: Setting this flag changes the exposure algorithm for OmniVision sensors
-	such that objects in the camera's view (i.e. your head) can be clearly
-	seen when they are illuminated from behind. It reduces or eliminates
-	the sensor's auto-exposure function, so it should only be used when
-	needed. Additionally, it is only supported with the OV6620 and OV7620.
-
-  NAME: unit_video
-  TYPE: Up to 16 comma-separated integers
-  DEFAULT: 0,0,0... (automatically assign the next available minor(s))
-  DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices.
-	For example, "unit_video=1,3" will make the driver use /dev/video1 and
-	/dev/video3 for the first two devices it detects. Additional devices
-	will be assigned automatically starting at the first available device
-	node (/dev/video0 in this case). Note that you cannot specify 0 as a
-	minor number. This feature requires kernel version 2.4.5 or higher.
-
-  NAME: remove_zeros
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (do not skip any incoming data)
-  DESC: Setting this to 1 will remove zero-padding from incoming data. This
-	will compensate for the blocks of corruption that can appear when the
-	camera cannot keep up with the speed of the USB bus (eg. at low frame
-	resolutions). This feature is always enabled when compression is on.
-
-  NAME: mirror
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (off)
-  DESC: Setting this to 1 will reverse ("mirror") the image horizontally. This
-	might be necessary if your camera has a custom lens assembly. This has
-	no effect with video capture devices.
-
-  NAME: ov518_color
-  TYPE: integer (Boolean)
-  DEFAULT: 0 (off)
-  DESC: Enable OV518 color support. This is off by default since it doesn't
-	work most of the time. If you want to try it, you must also load
-	ov518_decomp with the "nouv=0" parameter. If you get improper colors or
-	diagonal lines through the image, restart your video app and try again.
-	Repeat as necessary.
-
-WORKING FEATURES:
- o Color streaming/capture at most widths and heights that are multiples of 8.
- o Monochrome (use force_palette=1 to enable)
- o Setting/getting of saturation, contrast, brightness, and hue (only some of
-   them work the OV7620 and OV7620AE)
- o /proc status reporting
- o SAA7111A video capture support at 320x240 and 640x480
- o Compression support
- o SMP compatibility

-Linux driver for SE401 based USB cameras
-
-Copyright, 2001, Jeroen Vreeken
-
-
-INTRODUCTION:
-
-The SE401 chip is the used in low-cost usb webcams.
-It is produced by Endpoints Inc. (www.endpoints.com).
-It interfaces directly to a cmos image sensor and USB. The only other major
-part in a se401 based camera is a dram chip.
-
-The following cameras are known to work with this driver:
-
-Aox se401 (non-branded) cameras
-Philips PVCV665 USB VGA webcam 'Vesta Fun'
-Kensington VideoCAM PC Camera Model 67014
-Kensington VideoCAM PC Camera Model 67015
-Kensington VideoCAM PC Camera Model 67016
-Kensington VideoCAM PC Camera Model 67017
-
-
-WHAT YOU NEED:
-
--	USB support
--	VIDEO4LINUX support
-
-More information about USB support for linux can be found at:
-http://www.linux-usb.org
-
-
-MODULE OPTIONS:
-
-When the driver is compiled as a module you can also use the 'flickerless'
-option. With it exposure is limited to values that do not interfere with the
-net frequency. Valid options for this option are 0, 50 and 60. (0=disable,
-50=50hz, 60=60hz)
-
-
-KNOWN PROBLEMS:
-
-The driver works fine with the usb-ohci and uhci host controller drivers,
-the default settings also work with usb-uhci. But sending more than one bulk
-transfer at a time with usb-uhci doesn't work yet.
-Users of usb-ohci and uhci can safely enlarge SE401_NUMSBUF in se401.h in
-order to increase the throughput (and thus framerate).

 Purpose of the soc-camera subsystem
 -----------------------------------
 
-The soc-camera subsystem provides a unified API between camera host drivers and
-camera sensor drivers. It implements a V4L2 interface to the user, currently
-only the mmap method is supported.
+The soc-camera subsystem initially provided a unified API between camera host
+drivers and camera sensor drivers. Later the soc-camera sensor API has been
+replaced with the V4L2 standard subdev API. This also made camera driver re-use
+with non-soc-camera hosts possible. The camera host API to the soc-camera core
+has been preserved.
 
-This subsystem has been written to connect drivers for System-on-Chip (SoC)
-video capture interfaces with drivers for CMOS camera sensor chips to enable
-the reuse of sensor drivers with various hosts. The subsystem has been designed
-to support multiple camera host interfaces and multiple cameras per interface,
-although most applications have only one camera sensor.
+Soc-camera implements a V4L2 interface to the user, currently only the "mmap"
+method is supported by host drivers. However, the soc-camera core also provides
+support for the "read" method.
+
+The subsystem has been designed to support multiple camera host interfaces and
+multiple cameras per interface, although most applications have only one camera
+sensor.
 
 Existing drivers
 ----------------
 
-As of 2.6.27-rc4 there are two host drivers in the mainline: pxa_camera.c for
-PXA27x SoCs and sh_mobile_ceu_camera.c for SuperH SoCs, and four sensor drivers:
-mt9m001.c, mt9m111.c, mt9v022.c and a generic soc_camera_platform.c driver. This
-list is not supposed to be updated, look for more examples in your tree.
+As of 3.7 there are seven host drivers in the mainline: atmel-isi.c,
+mx1_camera.c (broken, scheduled for removal), mx2_camera.c, mx3_camera.c,
+omap1_camera.c, pxa_camera.c, sh_mobile_ceu_camera.c, and multiple sensor

-Linux driver for STV0680 based USB cameras
-
-Copyright, 2001, Kevin Sisson
-
-
-INTRODUCTION:
-
-STMicroelectronics produces the STV0680B chip, which comes in two
-types, -001 and -003. The -003 version allows the recording and downloading
-of sound clips from the camera, and allows a flash attachment. Otherwise,
-it uses the same commands as the -001 version. Both versions support a
-variety of SDRAM sizes and sensors, allowing for a maximum of 26 VGA or 20
-CIF pictures. The STV0680 supports either a serial or a usb interface, and
-video is possible through the usb interface.
-
-The following cameras are known to work with this driver, although any
-camera with Vendor/Product codes of 0553/0202 should work:
-
-Aiptek Pencam (various models)
-Nisis QuickPix 2
-Radio Shack 'Kid's digital camera' (#60-1207)
-At least one Trust Spycam model
-Several other European brand models
-
-WHAT YOU NEED:
-
--	USB support
--	VIDEO4LINUX support
-
-More information about USB support for linux can be found at:
-http://www.linux-usb.org
-
-
-MODULE OPTIONS:
-
-When the driver is compiled as a module, you can set a "swapRGB=1"
-option, if necessary, for those applications that require it
-(such as xawtv). However, the driver should detect and set this
-automatically, so this option should not normally be used.
-
-
-KNOWN PROBLEMS:
-
-The driver seems to work better with the usb-ohci than the usb-uhci host
-controller driver.
-
-HELP:
-
-The latest info on this driver can be found at:
-http://personal.clt.bellsouth.net/~kjsisson or at
-http://stv0680-usb.sourceforge.net

-Proposals for Extensions
-========================
+Adding Notify Callbacks
+=======================
+
+Sometimes the platform or bridge driver needs to be notified when a control
+from a sub-device driver changes. You can set a notify callback by calling
+this function:
 
-Some ideas for future extensions to the spec:
+void v4l2_ctrl_notify(struct v4l2_ctrl *ctrl,
+	void (*notify)(struct v4l2_ctrl *ctrl, void *priv), void *priv);
 
-1) Add a V4L2_CTRL_FLAG_HEX to have values shown as hexadecimal instead of
-decimal. Useful for e.g. video_mute_yuv.
+Whenever the give control changes value the notify callback will be called
+with a pointer to the control and the priv pointer that was passed with
+v4l2_ctrl_notify. Note that the control's handler lock is held when the
+notify function is called.
 
-2) It is possible to mark in the controls array which controls have been
-successfully written and which failed by for example adding a bit to the
-control ID. Not sure if it is worth the effort, though.
+There can be only one notify function per control handler. Any attempt
+to set another notify function will cause a WARN_ON.

-
-4. Overview
-===========
-This driver supports the video streaming capabilities of the devices mounting
-Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips. OV681
-based cameras should be supported as well.
-
-The driver is divided into two modules: the basic one, "w9968cf", is needed for
-the supported devices to work; the second one, "w9968cf-vpp", is an optional
-module, which provides some useful video post-processing functions like video
-decoding, up-scaling and colour conversions.
-
-Note that the official kernels do neither include nor support the second
-module for performance purposes. Therefore, it is always recommended to
-download and install the latest and complete release of the driver,
-replacing the existing one, if present.
-
-The latest and full-featured version of the W996[87]CF driver can be found at:
-http://www.linux-projects.org. Please refer to the documentation included in
-that package, if you are going to use it.
-
-Up to 32 cameras can be handled at the same time. They can be connected and
-disconnected from the host many times without turning off the computer, if
-your system supports the hotplug facility.
-
-To change the default settings for each camera, many parameters can be passed
-through command line when the module is loaded into memory.
-
-The driver relies on the Video4Linux, USB and I2C core modules. It has been
-designed to run properly on SMP systems as well. An additional module,
-"ovcamchip", is mandatory; it provides support for some OmniVision image
-sensors connected to the W996[87]CF chips; if found in the system, the module
-will be automatically loaded by default (provided that the kernel has been
-compiled with the automatic module loading option).
-
-
-5. Supported devices
-====================
-At the moment, known W996[87]CF and OV681 based devices are:
-- Aroma Digi Pen VGA Dual Mode ADG-5000 (unknown image sensor)
-- AVerMedia AVerTV USB (SAA7111A, Philips FI1216Mk2 tuner, PT2313L audio chip)
-- Creative Labs Video Blaster WebCam Go (OmniVision OV7610 sensor)
-- Creative Labs Video Blaster WebCam Go Plus (OmniVision OV7620 sensor)
-- Lebon LDC-035A (unknown image sensor)
-- Ezonics EZ-802 EZMega Cam (OmniVision OV8610C sensor)
-- OmniVision OV8610-EDE (OmniVision OV8610 sensor)
-- OPCOM Digi Pen VGA Dual Mode Pen Camera (unknown image sensor)
-- Pretec Digi Pen-II (OmniVision OV7620 sensor)
-- Pretec DigiPen-480 (OmniVision OV8610 sensor)
-
-If you know any other W996[87]CF or OV681 based cameras, please contact me.
-
-The list above does not imply that all those devices work with this driver: up
-until now only webcams that have an image sensor supported by the "ovcamchip"
-module work. Kernel messages will always tell you whether this is case.
-
-Possible external microcontrollers of those webcams are not supported: this
-means that still images cannot be downloaded from the device memory.
-
-Furthermore, it's worth to note that I was only able to run tests on my
-"Creative Labs Video Blaster WebCam Go". Donations of other models, for
-additional testing and full support, would be much appreciated.
-
-
-6. Module dependencies
-======================
-For it to work properly, the driver needs kernel support for Video4Linux, USB
-and I2C, and the "ovcamchip" module for the image sensor. Make sure you are not
-actually using any external "ovcamchip" module, given that the W996[87]CF
-driver depends on the version of the module present in the official kernels.
-
-The following options of the kernel configuration file must be enabled and
-corresponding modules must be compiled:
-
-	# Multimedia devices
-	#
-	CONFIG_VIDEO_DEV=m
-
-	# I2C support
-	#
-	CONFIG_I2C=m
-
-The I2C core module can be compiled statically in the kernel as well.
-
-	# OmniVision Camera Chip support
-	#
-	CONFIG_VIDEO_OVCAMCHIP=m
-
-	# USB support
-	#
-	CONFIG_USB=m
-
-In addition, depending on the hardware being used, only one of the modules
-below is necessary:
-
-	# USB Host Controller Drivers
-	#
-	CONFIG_USB_EHCI_HCD=m
-	CONFIG_USB_UHCI_HCD=m
-	CONFIG_USB_OHCI_HCD=m
-
-And finally:
-
-	# USB Multimedia devices
-	#
-	CONFIG_USB_W9968CF=m
-
-
-7. Module loading
-=================
-To use the driver, it is necessary to load the "w9968cf" module into memory
-after every other module required.
-
-Loading can be done this way, from root:
-
-	[root@localhost home]# modprobe usbcore
-	[root@localhost home]# modprobe i2c-core
-	[root@localhost home]# modprobe videodev
-	[root@localhost home]# modprobe w9968cf
-
-At this point the pertinent devices should be recognized: "dmesg" can be used
-to analyze kernel messages:
-
-	[user@localhost home]$ dmesg
-
-There are a lot of parameters the module can use to change the default
-settings for each device. To list every possible parameter with a brief
-explanation about them and which syntax to use, it is recommended to run the
-"modinfo" command:
-
-	[root@locahost home]# modinfo w9968cf
-
-

-10. Credits
-==========
-The development would not have proceed much further without having looked at
-the source code of other drivers and without the help of several persons; in
-particular:
-
-- the I2C interface to kernel and high-level image sensor control routines have
-  been taken from the OV511 driver by Mark McClelland;
-
-- memory management code has been copied from the bttv driver by Ralph Metzler,
-  Marcus Metzler and Gerd Knorr;
-
-- the low-level I2C read function has been written by Frederic Jouault;
-
-- the low-level I2C fast write function has been written by Piotr Czerczak.

-
-
-4. Overview and features
-========================
-This driver supports the video interface of the devices mounting the ZC0301 or
-ZC0301P Image Processors and Control Chips.
-
-The driver relies on the Video4Linux2 and USB core modules. It has been
-designed to run properly on SMP systems as well.
-
-The latest version of the ZC0301[P] driver can be found at the following URL:
-http://www.linux-projects.org/
-
-Some of the features of the driver are:
-
-- full compliance with the Video4Linux2 API (see also "Notes for V4L2
-  application developers" paragraph);
-- available mmap or read/poll methods for video streaming through isochronous
-  data transfers;
-- automatic detection of image sensor;
-- video format is standard JPEG;
-- dynamic driver control thanks to various module parameters (see "Module
-  parameters" paragraph);
-- up to 64 cameras can be handled at the same time; they can be connected and
-  disconnected from the host many times without turning off the computer, if
-  the system supports hotplugging;
-
-
-5. Module dependencies
-======================
-For it to work properly, the driver needs kernel support for Video4Linux and
-USB.
-
-The following options of the kernel configuration file must be enabled and
-corresponding modules must be compiled:
-
-	# Multimedia devices
-	#
-	CONFIG_VIDEO_DEV=m
-
-	# USB support
-	#
-	CONFIG_USB=m
-
-In addition, depending on the hardware being used, the modules below are
-necessary:
-
-	# USB Host Controller Drivers
-	#
-	CONFIG_USB_EHCI_HCD=m
-	CONFIG_USB_UHCI_HCD=m
-	CONFIG_USB_OHCI_HCD=m
-
-The ZC0301 controller also provides a built-in microphone interface. It is
-supported by the USB Audio driver thanks to the ALSA API:
-
-	# Sound
-	#
-	CONFIG_SOUND=y
-
-	# Advanced Linux Sound Architecture
-	#
-	CONFIG_SND=m
-
-	# USB devices
-	#
-	CONFIG_SND_USB_AUDIO=m
-
-And finally:
-
-	# V4L USB devices
-	#
-	CONFIG_USB_ZC0301=m
-
-
-6. Module loading
-=================
-To use the driver, it is necessary to load the "zc0301" module into memory
-after every other module required: "videodev", "v4l2_common", "compat_ioctl32",
-"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
-"uhci-hcd" or "ohci-hcd".
-
-Loading can be done as shown below:
-
-	[root@localhost home]# modprobe zc0301
-
-At this point the devices should be recognized. You can invoke "dmesg" to
-analyze kernel messages and verify that the loading process has gone well:
-
-	[user@localhost home]$ dmesg
-
-
-7. Module parameters
-====================
-Module parameters are listed below:
--------------------------------------------------------------------------------
-Name:           video_nr
-Type:           short array (min = 0, max = 64)
-Syntax:         <-1|n[,...]>
-Description:    Specify V4L2 minor mode number:
-		-1 = use next available
-		 n = use minor number n
-		You can specify up to 64 cameras this way.
-		For example:
-		video_nr=-1,2,-1 would assign minor number 2 to the second
-		registered camera and use auto for the first one and for every
-		other camera.
-Default:        -1
--------------------------------------------------------------------------------
-Name:           force_munmap
-Type:           bool array (min = 0, max = 64)
-Syntax:         <0|1[,...]>
-Description:    Force the application to unmap previously mapped buffer memory
-		before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
-		all the applications support this feature. This parameter is
-		specific for each detected camera.
-		0 = do not force memory unmapping
-		1 = force memory unmapping (save memory)
-Default:        0
--------------------------------------------------------------------------------
-Name:           frame_timeout
-Type:           uint array (min = 0, max = 64)
-Syntax:         <n[,...]>
-Description:    Timeout for a video frame in seconds. This parameter is
-		specific for each detected camera. This parameter can be
-		changed at runtime thanks to the /sys filesystem interface.
-Default:        2
--------------------------------------------------------------------------------
-Name:           debug
-Type:           ushort
-Syntax:         <n>
-Description:    Debugging information level, from 0 to 3:
-		0 = none (use carefully)
-		1 = critical errors
-		2 = significant information
-		3 = more verbose messages
-		Level 3 is useful for testing only, when only one device
-		is used at the same time. It also shows some information
-		about the hardware being detected. This module parameter can be
-		changed at runtime thanks to the /sys filesystem interface.
-Default:        2

-8. Supported devices
-====================
-None of the names of the companies as well as their products will be mentioned
-here. They have never collaborated with the author, so no advertising.
-
-From the point of view of a driver, what unambiguously identify a device are
-its vendor and product USB identifiers. Below is a list of known identifiers of
-devices mounting the ZC0301 Image Processor and Control Chips:
-

-9. Notes for V4L2 application developers
-========================================
-This driver follows the V4L2 API specifications. In particular, it enforces two
-rules:
-
-- exactly one I/O method, either "mmap" or "read", is associated with each
-file descriptor. Once it is selected, the application must close and reopen the
-device to switch to the other I/O method;
-
-- although it is not mandatory, previously mapped buffer memory should always
-be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
-The same number of buffers as before will be allocated again to match the size
-of the new video frames, so you have to map the buffers again before any I/O
-attempts on them.
-

+	---help---
+	  This module adds support for wireless adapter based on
+	  wil6210 chip by Wilocity. It supports operation on the
+	  60 GHz band, covered by the IEEE802.11ad standard.
+
+	  http://wireless.kernel.org/en/users/Drivers/wil6210

+config WIL6210_ISR_COR
+	bool "Use Clear-On-Read mode for ISR registers for wil6210"
+	depends on WIL6210
+	default y
+	---help---
+	  ISR registers on wil6210 chip may operate in either
+	  COR (Clear-On-Read) or W1C (Write-1-to-Clear) mode.
+	  For production code, use COR (say y); is default since
+	  it saves extra target transaction;
+	  For ISR debug, use W1C (say n); is allows to monitor ISR
+	  registers with debugfs. If COR were used, ISR would
+	  self-clear when accessed for debug purposes, it makes
+	  such monitoring impossible.
+	  Say y unless you debug interrupts

+/**
+ * WMI event receiving - theory of operations
+ *
+ * When firmware about to report WMI event, it fills memory area
+ * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
+ * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
+ *
+ * @wmi_recv_cmd reads event, allocates memory chunk  and attaches it to the
+ * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
+ * and handles events within the @wmi_event_worker. Every event get detached
+ * from list, processed and deleted.
+ *
+ * Purpose for this mechanism is to release IRQ thread; otherwise,
+ * if WMI event handling involves another WMI command flow, this 2-nd flow
+ * won't be completed because of blocked IRQ thread.

+/**
+ * Addressing - theory of operations
+ *
+ * There are several buses present on the WIL6210 card.
+ * Same memory areas are visible at different address on
+ * the different busses. There are 3 main bus masters:
+ *  - MAC CPU (ucode)
+ *  - User CPU (firmware)
+ *  - AHB (host)
+ *
+ * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
+ * AHB addresses starting from 0x880000
+ *
+ * Internally, firmware uses addresses that allows faster access but
+ * are invisible from the host. To read from these addresses, alternative
+ * AHB address must be used.
+ *
+ * Memory mapping
+ * Linker address         PCI/Host address
+ *                        0x880000 .. 0xa80000  2Mb BAR0

+TODO (general):
+==================================
+
+- User space interface refinement
+        - Controls should be used when possible rather than private ioctl
+        - No enums should be used
+        - Use of MC and V4L2 subdev APIs when applicable
+        - Single interface header might suffice
+        - Current interface forces to configure everything at once
+- Get rid of the dm365_ipipe_hw.[ch] layer
+- Active external sub-devices defined by link configuration; no strcmp
+  needed
+- More generic platform data (i2c adapters)
+- The driver should have no knowledge of possible external subdevs; see
+  struct vpfe_subdev_id
+- Some of the hardware control should be refactorede
+- Check proper serialisation (through mutexes and spinlocks)
+- Names that are visible in kernel global namespace should have a common
+  prefix (or a few)
+- While replacing the older driver in media folder, provide a compatibility
+  layer and compatibility tests that warrants (using the libv4l's LD_PRELOAD
+  approach) there is no regression for the users using the older driver.
+
+Building of uImage and Applications:
+==================================
+
+As of now since the interface will undergo few changes all the include
+files are present in staging itself, to build for dm365 follow below steps,
+
+- copy vpfe.h from drivers/staging/media/davinci_vpfe/ to
+  include/media/davinci/ folder for building the uImage.
+- copy davinci_vpfe_user.h from drivers/staging/media/davinci_vpfe/ to
+  include/uapi/linux/davinci_vpfe.h, and add a entry in Kbuild (required
+  for building application).
+- copy dm365_ipipeif_user.h from drivers/staging/media/davinci_vpfe/ to
+  include/uapi/linux/dm365_ipipeif.h and a entry in Kbuild (required
+  for building application).

+Introduction
+============
+
+This file documents the Texas Instruments Davinci Video processing Front End
+(VPFE) driver located under drivers/media/platform/davinci. The original driver
+exists for Davinci VPFE, which is now being changed to Media Controller
+Framework.
+
+Currently the driver has been successfully used on the following
+version of Davinci:
+
+	DM365/DM368
+
+The driver implements V4L2, Media controller and v4l2_subdev interfaces. Sensor,
+lens and flash drivers using the v4l2_subdev interface in the kernel are
+supported.
+
+
+Split to subdevs
+================
+
+The Davinci VPFE is split into V4L2 subdevs, each of the blocks inside the VPFE
+having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
+interface to userspace.
+
+	DAVINCI ISIF
+	DAVINCI IPIPEIF
+	DAVINCI IPIPE
+	DAVINCI CROP RESIZER
+	DAVINCI RESIZER A
+	DAVINCI RESIZER B
+
+Each possible link in the VPFE is modeled by a link in the Media controller
+interface. For an example program see [1].
+
+
+ISIF, IPIPE, and RESIZER block IOCTLs
+======================================
+
+The Davinci Video processing Front End (VPFE) driver supports standard V4L2
+IOCTLs and controls where possible and practical. Much of the functions provided
+by the VPFE, however, does not fall under the standard IOCTL's.
+
+In general, there is a private ioctl for configuring each of the blocks
+containing hardware-dependent functions.
+
+The following private IOCTLs are supported:
+
+	VIDIOC_VPFE_ISIF_[S/G]_RAW_PARAMS
+	VIDIOC_VPFE_IPIPE_[S/G]_CONFIG
+	VIDIOC_VPFE_RSZ_[S/G]_CONFIG
+
+The parameter structures used by these ioctl's are described in
+include/uapi/linux/davinci_vpfe.h.
+
+The VIDIOC_VPFE_ISIF_S_RAW_PARAMS, VIDIOC_VPFE_IPIPE_S_CONFIG and
+VIDIOC_VPFE_RSZ_S_CONFIG are used to configure, enable and disable functions in
+the isif, ipipe and resizer blocks respectively. These IOCTL's control several
+functions in the blocks they control. VIDIOC_VPFE_ISIF_S_RAW_PARAMS IOCTL
+accepts a pointer to struct vpfe_isif_raw_config as its argument. Similarly
+VIDIOC_VPFE_IPIPE_S_CONFIG accepts a pointer to struct vpfe_ipipe_config. And
+VIDIOC_VPFE_RSZ_S_CONFIG accepts a pointer to struct vpfe_rsz_config as its
+argument. Similarly VIDIOC_VPFE_ISIF_G_RAW_PARAMS, VIDIOC_VPFE_IPIPE_G_CONFIG
+and VIDIOC_VPFE_RSZ_G_CONFIG are used to get the current configuration set in
+the isif, ipipe and resizer blocks respectively.
+
+The detailed functions of the VPFE itself related to a given VPFE block is
+described in the Technical Reference Manuals (TRMs) --- see the end of the
+document for those.
+
+
+IPIPEIF block IOCTLs
+======================================
+
+The following private IOCTLs are supported:
+
+	VIDIOC_VPFE_IPIPEIF_[S/G]_CONFIG
+
+The parameter structures used by these ioctl's are described in
+include/uapi/linux/dm365_ipipeif.h
+
+The VIDIOC_VPFE_IPIPEIF_S_CONFIG is used to configure the ipipeif
+hardware block. The VIDIOC_VPFE_IPIPEIF_S_CONFIG and
+VIDIOC_VPFE_IPIPEIF_G_CONFIG accepts a pointer to struct ipipeif_params
+as its argument.
+

+ * Driver name : VPFE Capture driver
+ *    VPFE Capture driver allows applications to capture and stream video
+ *    frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ *    TVP5146 or  Raw Bayer RGB image data from an image sensor
+ *    such as Microns' MT9T001, MT9T031 etc.
+ *
+ *    These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ *    consists of a Video Processing Front End (VPFE) for capturing
+ *    video/raw image data and Video Processing Back End (VPBE) for displaying
+ *    YUV data through an in-built analog encoder or Digital LCD port. This
+ *    driver is for capture through VPFE. A typical EVM using these SoCs have
+ *    following high level configuration.
+ *
+ *    decoder(TVP5146/		YUV/

+ *    and to the input of VPFE through an optional MUX (if more inputs are

+ *    CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ *    does very little or no processing on YUV data and does pre-process Raw
+ *    Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ *    Color Space Conversion (CSC), data gain/offset etc. After this, data

+ *
+ *    Features supported
+ *		- MMAP IO
+ *		- USERPTR IO
+ *		- Capture using TVP5146 over BT.656
+ *		- Support for interfacing decoders using sub device model
+ *		- Work with DM365 or DM355 or DM6446 CCDC to do Raw Bayer
+ *		  RGB/YUV data capture to SDRAM.
+ *		- Chaining of Image Processor

- * ki_retry	-	iocb forward progress callback
- * @kiocb:	The kiocb struct to advance by performing an operation.
- *
- * This callback is called when the AIO core wants a given AIO operation
- * to make forward progress.  The kiocb argument describes the operation
- * that is to be performed.  As the operation proceeds, perhaps partially,
- * ki_retry is expected to update the kiocb with progress made.  Typically
- * ki_retry is set in the AIO core and it itself calls file_operations
- * helpers.
- *
- * ki_retry's return value determines when the AIO operation is completed
- * and an event is generated in the AIO event ring.  Except the special
- * return values described below, the value that is returned from ki_retry
- * is transferred directly into the completion ring as the operation's
- * resulting status.  Once this has happened ki_retry *MUST NOT* reference
- * the kiocb pointer again.
- *
- * If ki_retry returns -EIOCBQUEUED it has made a promise that aio_complete()
- * will be called on the kiocb pointer in the future.  The AIO core will
- * not ask the method again -- ki_retry must ensure forward progress.
- * aio_complete() must be called once and only once in the future, multiple
- * calls may result in undefined behaviour.
- *
- * If ki_retry returns -EIOCBRETRY it has made a promise that kick_iocb()
- * will be called on the kiocb pointer in the future.  This may happen
- * through generic helpers that associate kiocb->ki_wait with a wait
- * queue head that ki_retry uses via current->io_wait.  It can also happen
- * with custom tracking and manual calls to kick_iocb(), though that is
- * discouraged.  In either case, kick_iocb() must be called once and only
- * once.  ki_retry must ensure forward progress, the AIO core will wait
- * indefinitely for kick_iocb() to be called.

-	  currently in alpha-test, then the developers usually discourage
-	  uninformed widespread use of this feature by the general public to
-	  avoid "Why doesn't this work?" type mail messages. However, active
-	  testing and use of these systems is welcomed. Just be aware that it
-	  may not meet the normal level of reliability or it may fail to work
-	  in some special cases. Detailed bug reports from people familiar
-	  with the kernel internals are usually welcomed by the developers
-	  (before submitting bug reports, please read the documents
-	  <file:README>, <file:MAINTAINERS>, <file:REPORTING-BUGS>,
-	  <file:Documentation/BUG-HUNTING>, and

-	  scheduled to be removed in a future kernel release.

-	  falls into this category, or you have a situation that requires
-	  using these features, you should probably say N here, which will

+
+1. Run the guest:
+        'lkvm run -k [vmlinuz] -p "kgdboc=ttyS1 kgdbwait" --tty 1'
+
+And see which PTY got assigned to ttyS1 (you'll see:
+'  Info: Assigned terminal 1 to pty /dev/pts/X').
+
+2. Run GDB on the host:
+        'gdb [vmlinuz]'
+
+3. Connect to the guest (from within GDB):
+        'target remote /dev/pty/X'
+
+4. Start debugging! (enter 'continue' to continue boot).

+lkvm-balloon(1)
+================
+
+NAME
+----
+lkvm-balloon - Inflate or deflate the virtio balloon
+
+SYNOPSIS
+--------
+[verse]
+'lkvm balloon [command] [size] [instance]'
+
+DESCRIPTION
+-----------
+The command inflates or deflates the virtio balloon located in the
+specified instance.
+For a list of running instances see 'lkvm list'.
+
+Command can be either 'inflate' or 'deflate'. Inflate increases the
+size of the balloon, thus decreasing the amount of virtual RAM available
+for the guest. Deflation returns previously inflated memory back to the
+guest.

+General
+--------
+
+virtio-console as the name implies is a console over virtio transport. Here is
+a simple head to head comparison of the virtio-console vs regular 8250 console:
+
+8250 serial console:
+
+ - Requires CONFIG_SERIAL_8250=y and CONFIG_SERIAL_8250_CONSOLE=y kernel configs,
+which are enabled almost everywhere.
+ - Doesn't require guest-side changes.
+ - Compatible with older guests.
+
+virtio-console:
+
+ - Requires CONFIG_VIRTIO_CONSOLE=y (along with all other virtio dependencies),
+which got enabled only in recent kernels (but not all of them).
+ - Much faster.
+ - Consumes less processing resources.
+ - Requires guest-side changes.
+
+Enabling virtio-console
+------------------------
+
+First, make sure guest kernel is built with CONFIG_VIRTIO_CONSOLE=y. Once this
+is done, the following has to be done inside guest image:
+
+ - Add the following line to /etc/inittab:
+	'hvc0:2345:respawn:/sbin/agetty -L 9600 hvc0'
+ - Add 'hvc0' to /etc/securetty (so you could actually log on)
+ - Start the guest with '--console virtio'
+
+Common errors
+--------------
+
+Q: I don't see anything on the screen!
+A: Make sure CONFIG_VIRTIO_CONSOLE=y is enabled in the *guest* kernel, also
+make sure you've updated /etc/inittab
+
+Q: It won't accept my username/password, but I enter them correctly!
+A: You didn't add 'hvc0' to /etc/securetty

+Native Linux KVM tool
+=====================
+The goal of this tool is to provide a clean, from-scratch, lightweight
+KVM host tool implementation that can boot Linux guest images (just a
+hobby, won't be big and professional like QEMU) with no BIOS
+dependencies and with only the minimal amount of legacy device
+emulation.
+
+It's great as a learning tool if you want to get your feet wet in
+virtualization land: it's only 5 KLOC of clean C code that can already
+boot a guest Linux image.
+
+Right now it can boot a Linux image and provide you output via a serial
+console, over the host terminal, i.e. you can use it to boot a guest
+Linux image in a terminal or over ssh and log into the guest without
+much guest or host side setup work needed.
+
+1. To try out the tool, clone the git repository:
+
+  git clone git://github.com/penberg/linux-kvm.git
+
+or alternatively, if you already have a kernel source tree:
+
+  git remote add kvm-tool git://github.com/penberg/linux-kvm.git
+  git remote update
+  git checkout -b kvm-tool/master kvm-tool
+
+2. Compile the tool:
+
+  cd tools/kvm && make
+
+3. Download a raw userspace image:
+
+  wget http://wiki.qemu.org/download/linux-0.2.img.bz2 && bunzip2
+linux-0.2.img.bz2
+
+4. The guest kernel has to be built with the following configuration:
+
+ - For the default console output:
+	CONFIG_SERIAL_8250=y
+	CONFIG_SERIAL_8250_CONSOLE=y
+
+ - For running 32bit images on 64bit hosts:
+	CONFIG_IA32_EMULATION=y
+
+ - Proper FS options according to image FS (e.g. CONFIG_EXT2_FS, CONFIG_EXT4_FS).
+
+ - For all virtio devices listed below:
+	CONFIG_VIRTIO=y
+	CONFIG_VIRTIO_RING=y
+	CONFIG_VIRTIO_PCI=y
+
+ - For virtio-blk devices (--disk, -d):
+	CONFIG_VIRTIO_BLK=y
+
+ - For virtio-net devices ([--network, -n] virtio):
+	CONFIG_VIRTIO_NET=y
+
+ - For virtio-9p devices (--virtio-9p):
+	CONFIG_NET_9P=y
+	CONFIG_NET_9P_VIRTIO=y
+	CONFIG_9P_FS=y
+
+ - For virtio-balloon device (--balloon):
+	CONFIG_VIRTIO_BALLOON=y
+
+ - For virtio-console device (--console virtio):
+	CONFIG_VIRTIO_CONSOLE=y
+
+ - For virtio-rng device (--rng):
+	CONFIG_HW_RANDOM_VIRTIO=y
+
+ - For vesa device (--sdl or --vnc):
+	CONFIG_FB_VESA=y
+
+
+5. And finally, launch the hypervisor:
+
+  ./lkvm run --disk linux-0.2.img \
+	    --kernel ../../arch/x86/boot/bzImage \
+or
+
+  sudo ./lkvm run --disk linux-0.2.img \
+		 --kernel ../../arch/x86/boot/bzImage \
+		 --network virtio
+
+The tool has been written by Pekka Enberg, Cyrill Gorcunov, Asias He,
+Sasha Levin and Prasad Joshi. Special thanks to Avi Kivity for his help
+on KVM internals and Ingo Molnar for all-around support and encouragement!
+
+See the following thread for original discussion for motivation of this
+project:
+
+http://thread.gmane.org/gmane.linux.kernel/962051/focus=962620
+
+Build dependencies
+=====================
+For deb based systems:
+32-bit:
+sudo apt-get install build-essential
+64-bit:
+sudo apt-get install build-essential libc6-dev-i386
+
+For rpm based systems:
+32-bit:
+yum install glibc-devel
+64-bit:
+yum install glibc-devel glibc-static
+
+On 64-bit Arch Linux make sure the multilib repository is enabled in your
+/etc/pacman.conf and run
+pacman -Sy lib32-glibc
