Subject: [PATCH v3 00/11] MediaTek DDP GAMMA - 12-bit LUT support

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!
