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/serial/brcm,bcm7271-uart.yaml: 'additionalProperties' is a required property
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/serial/brcm,bcm7271-uart.yaml: ignoring, error in schema: 
warning: no schema found in file: ./Documentation/devicetree/bindings/serial/brcm,bcm7271-uart.yaml

See https://patchwork.ozlabs.org/patch/1427364

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.
