Thanks for the input!

AFAIU, Rx only is currently not a valid description. As you are
providing a description list with minItems =3D <1>, I think it expects
either the first item or nothing. When I change the example in the yaml
to only give the "rx" interrupt, make dt_binding_check errors out.

I will propose an update.

Thanks,
