[PATCH v3 41/47] arm64: dts: qcom: sm8250: Add GCC CX power domain

From: Abel Vesa <hidden>
Date: 2026-08-24 11:56:43
Also in: linux-arm-msm, linux-clk, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

The GCC GDSCs on SM8250 are backed by the RPMh CX power domain. Without
describing that parent domain, consumers of GCC-provided GDSCs can enable
their local domain without causing the required CX vote to be held.

Add the CX power-domain reference to the GCC node so votes from GCC GDSC
consumers can propagate to RPMh CX.
