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:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/firmware/arm,scmi.example.dtb: scmi: mbox-names: ['tx'] is too short
	From schema: /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/firmware/arm,scmi.yaml
Documentation/devicetree/bindings/firmware/arm,scmi.example.dtb:0:0: /example-3/soc/mailbox@...00000: failed to match any schema with compatible: ['qcom,cpucp-mbox']

doc reference errors (make refcheckdocs):

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

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.
