mt8183 gamma module usage is different with before soc, gamma odd(index start from 0) lut value set to hardware register should be the difference of current lut value with last lut value. for example, chrome os user space set lut like this(only r chanel for example): 2 4 6 8 10 12. 1) mt8183 gamma driver should set the gamma lut to hardware register like this: 2 [2] 6 [2] 10 [2] the value with [] is the difference value 2)gamma hardware process display data with original lut Link: https://patchwork.kernel.org/project/linux-mediatek/patch/20220428085829.15855-2-yongqiang.niu@mediatek.com/ Signed-off-by: Yongqiang Niu <yongqiang.niu@mediatek.com> Signed-off-by: Yongqiang Niu <yongqiang.niu@mediatek.corp-partner.google.com> Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Signed-off-by: Chun-Kuang Hu <chunkuang.hu@kernel.org>
