The Renesas Camera Receiver Unit in the RZ/V2H SoC can output RAW data captured from an image sensor without conversion to an RGB/YUV format. In that case the data are packed into 64-bit blocks, with a variable amount of padding in the most significant bits depending on the bitdepth of the data. Add new V4L2 pixel format codes for the new formats, along with documentation to describe them.

Description
|
|
===========
|
|
|
|
These pixel formats are some of the RAW outputs for the Camera Receiver Unit in
|
|
the Renesas RZ/V2H SoC. They are raw formats which pack pixels contiguously into
|
|
64-bit units, with the 4 or 8 most significant bits padded.
