I don't think Rob has seen the new interrupt range thing?
(It's not a big deal. Things like these are a bit fuzzy.)

If it is as you say, that other SoCs are doing the same, we should
think about creating a generic property for this. Like
hierarchy-interrupt-ranges or so.

I kind of liked the old patch where it was just "interrupts" and
then you looked it up from the irq subsystem. (tglx even ACKed
the patch).

But I want the DT people to say something here.
