[PATCH v3 40/47] arm64: dts: qcom: sm8150: Add GCC CX power domain

From: Abel Vesa

Date: Mon Aug 24 2026 - 08:07:00 EST


The GCC GDSCs on SM8150 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.
