[PATCH 11/16] arm64: dts: qcom: sm8450: Add GCC CX power domain
From: Abel Vesa
Date: Wed Aug 19 2026 - 08:59:11 EST
The GCC GDSCs on SM8450 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.
