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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/reset/renesas,rzv2h-usb2phy-reset.example.dtb: reset-controller@15830000 (renesas,r9a09g057-usb2phy-reset): $nodename:0: 'reset-controller@15830000' does not match '^mux-controller(@.*|-([0-9]|[1-9][0-9]+))?$'

See https://patchwork.kernel.org/project/devicetree/patch/af75145b08e24034dcf367932002079363e5dd81.1769704000.git.tommaso.merciai.xr@xxxxxxxxxxxxxx

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.
