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

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):
Warning: Documentation/devicetree/bindings/gpio/maxim,max77759-gpio.yaml references a file that doesn't exist: Documentation/devicetree/bindings/mfd/maxim,max77759.yaml
Documentation/devicetree/bindings/gpio/maxim,max77759-gpio.yaml: Documentation/devicetree/bindings/mfd/maxim,max77759.yaml

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250325-max77759-mfd-v6-1-c0870ca662ba@linaro.org

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.
