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:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/display/mediatek/mediatek,hdmi-ddc.example.dt.yaml:0:0: /example-0/i2c@...12000: failed to match any schema with compatible: ['mediatek,mt8173-hdmi-ddc']
Documentation/devicetree/bindings/display/mediatek/mediatek,cec.example.dt.yaml:0:0: /example-0/cec@...13000: failed to match any schema with compatible: ['mediatek,mt8173-cec']

See https://patchwork.ozlabs.org/patch/1465094

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.
