Subject: arm64: dts: qcom: milos: Add missing CX power domain to GCC
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e46b48b853122626806d989d5db4ce97eaaac2ca;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: qcom: milos: Add missing CX power domain to GCC

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.
