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/iio/adc/nuvoton,ma35d1-eadc.yaml: properties:interrupts: {'minItems': 1, 'maxItems': 4, 'items': [{'description': 'ADINT0 end-of-conversion interrupt'}, {'description': 'ADINT1 end-of-conversion interrupt'}, {'description': 'ADINT2 end-of-conversion interrupt'}, {'description': 'ADINT3 end-of-conversion interrupt'}]} should not be valid under {'required': ['maxItems']}
	hint: "maxItems" is not needed with an "items" list

See https://patchwork.kernel.org/project/devicetree/patch/20260713081127.115197-2-cwweng.linux@gmail.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.
