[PATCH RFC 22/24] arm64: dts: qcom: sm8550: Describe GPU_CC power plumbing requirements

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

A number of power rails must be powered on in order for GPU_CC to
function. Ensure that's conveyed to the OS.

Fixes: 9f7579423d2d ("arm64: dts: qcom: sm8550: Add graphics clock controller")
