My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/gpio/aspeed,ast2400-gpio.example.dtb: gpio@1e780000: '#interrupt-cells' is a required property
from schema $id: http://devicetree.org/schemas/gpio/aspeed,ast2400-gpio.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

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.

The original binding does not require this clock, but I can't help but
wonder if it should be required. I suspect that this peripheral does
not actually work if a clock is not provided to it. Whether or not the
rate of the clock is then used by the driver for debounce timings or
whatever is a different question.

Otherwise though, this looks fine to me.
