9d0a79e55a media: Documentation: v4l: Document required controls on camera sensors 
Raw camera sensors connected to parallel or CSI-2 busses need to implement
V4L2_CID_LINK_FREQ control so receiver drivers can configure the hardware
accordingly.

Document this. Also say V4L2_CID_PIXEL_RATE is recommended for such
hardware.

e4cf8c58af media: Documentation: media: Document how to write camera sensor drivers 
While we have had some example drivers, there has been up to date no
formal documentation on how camera sensor drivers should be written; what
are the practices, why, and where they apply.
