gpu: ipu-v3: Fix U/V offset macros for planar 4:2:0
The U and V offset macros for planar 4:2:0 (U_OFFSET, V_OFFSET, and UV_OFFSET), are not correct. The height component to the offset was calculated as: (pix->width * y / 4) But this does not produce correct offsets for odd values of y (luma line #). The luma line # must be decimated by two to produce the correct U/V line #, so the correct formula is: (pix->width * (y / 2) / 2) Signed-off-by: Steve Longerbeam <> Signed-off-by: Philipp Zabel <>
