we add the format in DRM driver.

nit: probably better to alphabetize these (UYVY before YUVU).

Your patch looks good, but I am not sure about some details.
AFAIK, there is a color matrix here to describe how to transform from
BT.601 / BT.709 / other color space to RGB color space. You can use the
default value if you don't care how colors are represented. Or you can
specify the matrix in this patch.
