I dont think this is correct, the case PLANE_CTL_FORMAT_NV12 is defined
as (1 << 24) but when I check bspec definition, 24th bit is set for
P010/12/16 formats. AFAIK NV12 is 8 bit format whereas P0xx formats are
10/12/16 bit formats (they both are YCBCR 4:2:0 of course). This means
we have mixed NV12 format with P0xx formats. When I checked the
definition of DRM_FORMAT_NV12, I am not sure if that's intended for
this. Ville, I saw that the DRM_FORMAT_NV12 definition was added by you,
can you please comment if this is the right usage ?
