Very nice.

Please make the subject prefix "arm64: dts: qcom: sc8280xp:", to match
other changes in the sc8280xp.dtsi.

No need to repeat this comment, its purpose is to indicate that nodes
above are sorted alphabetically and pinctrl-related nodes are kept here
at the end of the file. Please place your nodes below the existing /*

Thanks,
