/*
* Sub-devices are devices that are connected somehow to the main bridge
* device. These devices are usually audio/video muxers/encoders/decoders or
* sensors and webcam controllers.
*
* Usually these devices are controlled through an i2c bus, but other buses
* may also be used.
*
* The v4l2_subdev struct provides a way of accessing these devices in a
* generic manner. Most operations that these sub-devices support fall in
* a few categories: core ops, audio ops, video ops and tuner ops.
*
* More categories can be added if needed, although this should remain a
* limited set (no more than approx. 8 categories).
*
* Each category has its own set of ops that subdev drivers ca
