Hi Jonas Karlman,
Is there an another yuv 10bit format with 4:4:4 sub-simpling but
has no padding?
Maybe we can call it DRM_FORMAT_NV30:
{ .format = DRM_FORMAT_NV30, .depth = 0,
.num_planes = 2, .char_per_block = { 5, 5, 0 },
.block_w = { 4, 2, 0 }, .block_h = { 1, 1, 0 }, .hsub = 1,
.vsub = 1, .is_yuv = true },
this format can supported by rockchip rk3288/rk3399... platform, can you
add this format at this series patches?

I will send a v2 including this 4:4:4 format later this weekend. Is there any hw block on rk3288/rk3399 that can produce a buffer in such format? If I am not mistaken rkvdec only support 10-bit h264 in 4:2:0/4:2:2 and hevc 4:2:0 10-bit, those are the formats I have been able to test so far.
