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]

If you send out someone else's patches, you need to add your own signed-off-by too.
Also, I pointed out that other people are also working on P010 formats, but the coordination here didn't seem to have happened. Other patch will land in drm-misc rsn, so pls drop your patch here and for merging this means a backmerge.
Thanks, Daniel
