+/* 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:
+
+   g_chip_ident
+   log_status
+   g_register
+   s_register
+
+   This provides basic debugging support.
+
+   The ioctl ops is meant for generic ioctl-like commands. Depending on
+   the use-case it might be better to use subdev-specific ops (currently
+   not yet implemented) since ops provide proper type-checking.
