This now fails with:

arch/arm64/boot/dts/qcom/sc8280xp-crd.dtb: display-controller at ae01000: 
ports: 'port at 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 at 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 at 0 / port at 1 ?
