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

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/gpio/mrvl-gpio.example.dt.yaml: gpio@...00000: 'ranges' is a required property


If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+ --upgrade

Please check and re-submit.
