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!
