Add P212, P410 and P412 formats, including their FourCC codes and drm_format_info entries. - P212 is a two-plane, 12-bit, 4:2:2 YCbCr format - P410 is a two-plane, 10-bit, 4:4:4 YCbCr format - P412 is a two-plane, 12-bit, 4:4:4 YCbCr format Assisted-by: Cursor:GPT-5.5 Signed-off-by: Jonah Walker <redacted> --- drivers/gpu/drm/drm_fourcc.c | 12 ++++++++++++ include/uapi/drm/drm_fourcc.h | 21 +++++++++++++++++++++ 2 files changed, 33 insertions(+)
