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/arm/bcm/raspberrypi,bcm2835-firmware.example.dt.yaml: firmware: pwm:#pwm-cells:0:0: 2 was expected
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/arm/bcm/raspberrypi,bcm2835-firmware.yaml


See https://patchwork.ozlabs.org/patch/1393804

The base for the patch is generally the last rc1. Any dependencies
should be noted.

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.
