Does not the following:
"Nodes that describe devices which generate interrupts must contain an
"interrupts" property, an "interrupts-extended" property, or both. If
both are
present, the latter should take precedence; the former may be provided
simply
for compatibility with software that does not recognize the latter."
already makes it clear that 'interrupts-extended' is the preferred way
to represent interrupts?
