[PATCH v3 05/15] drm/msm/dp: fold dp_power into dp_ctrl module
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Thu Jan 25 23:02:34 UTC 2024
The dp_power submodule is limited to handling the clocks only following
previous cleanups. Fold it into the dp_ctrl submodule, removing one
unnecessary level of indirection.
