There is an issue here. You are describing the properties beneath the 
port@1, while in reality they are found beneath the endpoint node. See 
analogix,anx7625.yaml for a proper example.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/display/msm/dp-controller.yaml:108:21: [error] syntax error: mapping values are not allowed here (syntax)

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/1670432278-30643-3-git-send-email-quic_khsieh@quicinc.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
