Hi Dave, Daniel,
please consider merging these image converter fixes for v5.4, which
avoid image degradation due to intermediate downscaling in some tiled
conversions and fix 1:1 conversions that are multiples of the hardware
tile size. This also adds RGBX and BGRX format support now that these
are defined for V4L2, and there is a patch to remove a leftover line
from the Makefile.
regards
Philipp

drm/imx: IPUv3 image converter fixes and improvements
Fix image converter seam handling for 1024x1024 pixel hardware
limitation at the main processing section input, improve error
handling, and slightly optimize for 1:1 conversions.
Add support for newly defined 32-bit RGB V4L2 pixel formats.
