+/* 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 busses
+ 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 can implement.
+
+ A subdev driver can leave the pointer to the category ops NULL if
+ it does not implement them (e.g. an audio subdev will generally not
+ implement the video category ops). The exception is the core category:
+ this must always be present.
+
+ These ops are all used internally so it is no problem to change, remove
+ or add ops or move ops from one to another category. Currently these
+ ops are based on the original ioctls, but since ops are not limited to
+ one argument there is room for improvement here once all i2c subdev
+ drivers are converted to use these ops.
+ */

+/* Core ops: it is highly recommended to implement at least these ops:

+

+ the use-case it might be better to use subdev-specific ops (currently
+ not yet implemented) since ops provide proper type-checking.
