Changes in v5: - Removed incorrect comment on default LUT size and bits - Removed useless check for num_lut_banks - Added comment about CMDQ implementation on patch 5 - Evaluated passing lut size/bits from AAL, idea discarded as the implementation would be rather tricky while bringing no benefits. Changes in v4: - Fixed assignment typo appeared in v3 Changes in v3: - Fixed issues due to variables renaming during cleanup (oops) - This is actually the right series, since v2 was taken from the wrong kernel tree.... :-) Changes in v2: - Added explicit inclusion of linux/bitfield.h in patch [06/11] This series adds support for GAMMA IP requiring and/or supporting a 12-bits LUT using a slightly different register layout and programming sequence for multiple LUT banks: this IP version is currently found on a number of SoCs, not only including the Chromebook/IoT oriented Kompanio 1200/1380 MT8195/MT8195T, but also Smartphone chips such as the Dimensity 9200 (MT6985) and others. This series was tested on MT8195, MT8192, MT8173, MT6795: * MT6795, MT8192, MT8173: No regression, works fine. * MT8195: Color correction is finally working!
