Out of interest, and to learn the correct terminology for future
reference, I thought I'd ask:

Are the integer cells _the_ "specifier" which complements the
"phandle"?  Or does the "specifier" _consist_ of a phandle _and_
a (potentially empty) set of integer cells which all together
uniqely specify the resource?

For clocks and gpios I would tend towards the latter model, it
feels more intuitive to me.  I always felt interrupts to be the
exception in that their parent and the integer cells are spread
across individual properties.  Which in itself poses a
limitation, and I've seen patches trying to bring those two parts
of the specification together, such that members of a list of
interrupts can reference items from different parents.
