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/linux-dt-review/Documentation/devicetree/bindings/pinctrl/brcm,ns-pinmux.example.dt.yaml: cru@1800c100: $nodename:0: 'cru@1800c100' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
	From schema: /usr/local/lib/python3.8/dist-packages/dtschema/schemas/simple-bus.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1538413

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.
