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/clock/renesas,cpg-div6-clock.example.dtb: cpg_clocks@e6150000 (renesas,r8a73a4-cpg-clocks): clock-output-names: ['main', 'pll0', 'pll1', 'pll2', 'pll2s', 'pll2h', 'z', 'z2', 'i', 'm3', 'b', 'm1', 'm2', 'zx', 'zs', 'hp'] is too short

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260502185557.93061-2-marek.vasut+renesas@xxxxxxxxxxx

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.
