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

yamllint warnings/errors:
./Documentation/devicetree/bindings/pinctrl/rockchip,pinctrl.yaml:88:11: [error] string value is redundantly quoted with any quotes (quoted-strings)

dtschema/dtc warnings/errors:

See https://patchwork.kernel.org/project/devicetree/patch/20251216112053.1927852-7-ye.zhang@rock-chips.com

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.
