Re: [PATCH] drm/rockchip: Require the YTR modifier for AFBC

The AFBC decoder used in the Rockchip VOP assumes the use of the YUV-like colourspace transform (YTR). YTR is lossless for RGB(A) buffers, which covers the RGBA8 and RGB565 formats supported in vop_convert_afbc_format. Use of YTR is signaled with the AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As such, a producer would have to generate buffers that do not use YTR, which the VOP would erroneously decode as YTR, leading to severe visual corruption.

Applied, thanks!
