+ * Framework to handle complex IIO aggregate devices.
+ *
+ * The typical architecture is to have one device as the frontend device which
+ * can be "linked" against one or multiple backend devices. All the IIO and
+ * userspace interface is expected to be registers/managed by the frontend
+ * device which will callback into the backends when needed (to get/set some
+ * configuration that it does not directly control).
+ *
+ *                                           -------------------------------------------------------
+ * ------------------                        | ------------         ------------      -------  FPGA|
+ * |     ADC        |------------------------| | ADC CORE |---------| DMA CORE |------| RAM |      |
+ * | (Frontend/IIO) | Serial Data (eg: LVDS) | |(backend) |---------|          |------|     |      |
+ * |                |------------------------| ------------         ------------      -------      |
+ * ------------------                        -------------------------------------------------------
+ *
+ * The framework interface is pretty simple:
+ *   - Backends should register themselves with devm_iio_backend_register()
+ *   - Frontend devices should get backends with devm_iio_backend_get()
+ *
+ * Also to note that the primary target for this framework are converters like
+ * ADC/DACs so iio_backend_ops will have some operations typical of converter
+ * devices. On top of that, this is "generic" for all IIO which means any kind
+ * of device can make use of the framework. That said, If the iio_backend_ops
+ * struct begins to grow out of control, we can always refactor things so that
+ * the industrialio-backend.c is only left with the really generic stuff. Then,
+ * we can build on top of it depending on the needs.
