[PATCH v2 2/9] drm/msm/dpu: simplify CDP programming
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Tue May 2 15:05:26 UTC 2023
Get rid of intermediatory configuration structure and defines. Pass the
format and the enablement bit directly to the new helper. The
WB_CDP_CNTL register ignores BIT(2), so we can write it for both SSPP
and WB CDP settings.
