This now fails with:

arch/arm64/boot/dts/qcom/sc8280xp-crd.dtb: display-controller@ae01000: ports: 'port@0' is a required property From schema: Documentation/devicetree/bindings/display/msm/qcom,sc8280xp-dpu.yaml arch/arm64/boot/dts/qcom/sc8280xp-crd.dtb: display-controller@ae01000: Unevaluated properties are not allowed ('ports' was unexpected) From schema: Documentation/devicetree/bindings/display/msm/qcom,sc8280xp-dpu.yaml

We do not map reg ids to INTF indices. So, unless you plan to change that, could you please change these to port@0 / port@1 ?

[skipped the rest]
