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.

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

[PATCH] drm/mediatek: Support UYVY and YUYV format for overlay

2016-12-13 Thread Bibby Hsieh 
MT8173 overlay can support UYVY and YUYV format,
we add the format in DRM driver.
