Looking better. :) Please CC dri-devel next time.

[Intel-gfx] [PATCH v2 1/4] drm: Add P010, P012, P016 format definitions and fourcc

2018-06-12 Thread Juha-Pekka Heikkila 
Add P010 definition, semi-planar yuv format where each component
is 16 bits 10 msb containing color value. First come Y plane [10:6]
followed by 2x2 subsampled Cr:Cb plane [10:6:10:6]

Add P012 definition, semi-planar yuv format where each component
is 16 bits 12 msb containing color value. First come Y plane [12:4]
followed by 2x2 subsampled Cr:Cb plane [12:4:12:4]

Add P016 definition, semi-planar yuv format where each component
is 16 bits. First come Y plane followed by 2x2 subsampled Cr:Cb
plane [16:16]
