| Message-ID | <sOa8V-2mt-3@gated-at.bofh.it> |
MT8173 overlay can support UYVY and YUYV format, we add the format in DRM driver.

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.
