Subject[Patch v2 19/21] media: v4l2-common: add pixel encoding support
Date
It is often useful to figure out if a pixel_format is either YUV or RGB
especially for driver who can perform the pixel encoding conversion.

Instead of having each driver implement its own "is_this_yuv/rgb"
function based on a restricted set of pixel value, it is better to do
this in centralized manner.

We therefore add a pix_enc member to the v4l2_format_info structure to
quickly identify the related pixel encoding.
And add helper function to find/check pixel encoding.
