Perhaps this should go into some more generic document (perhaps
something like Documentation/devicetree/bindings/interrupts.txt) to
describe the common properties for interrupt controllers and refer to
that document in bindings that use them.

It might be good to document the #interrupt-cells property as well, with
the common meaning as defined by the various irq_domain_ops.xlate()

Do you want me to replace occurrences of this in other binding documents
by a reference to the new document while I'm at it?
