This GPIO controller is used on UniPhier SoC family.

The vendor specific property "socionext,interrupt-ranges" is for
specifying interrupt mapping to the parent interrupt controller
because the mapping is not contiguous.  It works like "ranges",
but transforms "interrupts" instead of "reg".

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.)

+               socionext,interrupt-ranges = <0 48 16>, <16 154 5>, <21 217 3>;

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.
