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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/devfreq/event/rockchip,dfi.yaml: properties:clock-names: {'minItems': 1, 'maxItems': 4, 'items': [{'enum': ['pclk_ddr_mon', 'pclk_ddr_mon_ch0']}, {'const': 'pclk_ddr_mon_ch1'}, {'const': 'pclk_ddr_mon_ch2'}, {'const': 'pclk_ddr_mon_ch3'}]} should not be valid under {'required': ['maxItems']}

See https://patchwork.kernel.org/project/devicetree/patch/20260917-b4-rockchip-dfi-rk3576-support-v1-3-a5752a29f7bd@collabora.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.
