[PATCH 0/2] dt-bindings: display: qcom,sm8[56]50-mdss: only document the mdp0-mem interconnect path

[Neil Armstrong]

The mdp1-mem is not supported on the SM8550 & SM8650 SoCs, so only support a single
mdp0-mem interconnect entry.

This fixes the following errors:
display-subsystem@ae00000: interconnects: [[200, 3, 7, 32, 1, 7]] is too short
        from schema $id: http://devicetree.org/schemas/display/msm/qcom,sm8650-mdss.yaml#
display-subsystem@ae00000: interconnect-names: ['mdp0-mem'] is too short
        from schema $id: http://devicetree.org/schemas/display/msm/qcom,sm8650-mdss.yaml#

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250207-topic-sm8x50-mdss-interconnect-bindings-fix-v1-1-852b1d6aee46@linaro.org

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.

No, please add cpu-cfg interconnect instead.
