Hello Krzysztof,
Thanks for your review.
The difference of disp_aal for each MediaTek SoCs is "has_gamma".
And we only control this variable for different MediaTek SoCs.
The value of has_gamma for MT8173 is true.
The value of has_gamma for MT8183 is false. (Moreover, the driver data
is null for MT8183)
From this situation, I think it's not compatible between MT8173 and
MT8183.
