This is just enum.

Keep entries ordered alphabetically. In compatible list as well.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.
interrupts can be max 17, so just test it and you will see errors.
Why names are not listed? If you accept names like "candy" or
"elephant", then why having the names in the first place?
And what about clocks?
