SubjectRe: [PATCH v2 1/4] clk: qcom: gdsc: Handle GDSC regulator supplies
From
Date
Quoting Bjorn Andersson (2020-04-17 00:00:41)
> Certain GDSCs, such as the GPU_GX on MSM8996, requires that the upstream
> regulator supply is powered in order to be turned on.
>
> It's not guaranteed that the bootloader will leave these supplies on and
> the driver core will attempt to enable any GDSCs before allowing the
> individual drivers to probe defer on the PMIC regulator driver not yet
> being present.
>
> So the gdsc driver needs to be made aware of supplying regulators and
> probe defer on their absence, and it needs to enable and disable the
> regulator accordingly.
>
> Voltage adjustments of the supplying regulator are deferred to the
> client drivers themselves.
