[PATCH 5/6] arm64: dts: qcom: sm8550: Add missing CX power domain to GCC
From: Neil Armstrong
Date: Fri Apr 24 2026 - 05:12:39 EST
Unless CX is declared as the power-domain of GCC, votes (power and
performance) on the GDSCs it provides will not propagate to the CX,
which might result in under-voltage conditions.
Add the missing power-domains property to associate GCC with RPMHPD_CX.
Fixes: ffc50b2d3828 ("arm64: dts: qcom: Add base SM8550 dtsi")
