X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=64b00da69ef6e2cb113868c3ecdccd9bbc1fc91d;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: cix: add FCH(S0)/S5 GPIO controllers for sky1

Add Cadence GPIO controller nodes for Sky1 FCH(S0) and S5 domains in
sky1.dtsi, and enable those controllers on sky1-orion-o6.
