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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/bridge/analogix,anx7625.example.dt.yaml: encoder@58: ports: '#address-cells', '#size-cells' do not match any of the regexes: 'pinctrl-[0-9]+'
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/bridge/analogix,anx7625.yaml

See https://patchwork.ozlabs.org/patch/1431199

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.

Sounds like a boolean.

You're going to need to rebase this one drm-misc-next which uses the 
graph schema now.
