All the platforms from the renesas,rzg2l-pinctrl.yaml binding
actually require the interrupt-parent property. Add it.

But they don't require it. It *never* is required. If interrupt-parent 
is not found in a node, the parent will be checked.

The check failure is because the example extraction has to play with 
interrupt-parent to make interrupt parsing work.

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/pinctrl/renesas,rzg2l-pinctrl.example.dtb: pinctrl@11030000: 'interrupt-parent' is a required property
	from schema $id: http://devicetree.org/schemas/pinctrl/renesas,rzg2l-pinctrl.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240917173249.158920-2-fabrizio.castro.jz@renesas.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.
