[PATCH v4 3/8] clk: qcom: gpucc-sc8280xp: Add external supply for GX gdsc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On SA8295P and SA8540P the GFX rail is powered by a dedicated external
regulator, instead of the rpmh-controlled "gfx.lvl".

Define the "vdd-gfx" as the supply regulator for the GDSC, to cause the
gdsc logic to look for, and control, this external power supply.
