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:
Documentation/devicetree/bindings/gpio/brcm,kona-gpio.example.dts:21.23-34.11: Warning (interrupts_property): /example-0/gpio@...03000: Missing interrupt-parent
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/gpio/brcm,kona-gpio.example.dtb: gpio@...03000: interrupts: [[0], [106], [4], [0], [115], [4], [0], [114], [4], [0], [113], [4], [0], [112], [4], [0], [111], [4]] is too long
	from schema $id: http://devicetree.org/schemas/gpio/brcm,kona-gpio.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/ZMQU7ap9CxfY5eIu@standask-GA-A55M-S2HP

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
