I put it on a separate branch in the GPIO tree (gpio-irqchip-rework)
then pulled that into the devel branch of both GPIO and
pin control. That should do it.

If there are compile bugs, we shake them out now, then we
stabilize this into v4.15.

THANKS A LOT MAN, this was really walking the extra mile for
the GPIO subsystem so it is much, much appreciated. I hope
this will be the silver bullet that make it possible to consolidate
and manage the "banked GPIO" controllers going forward so
I don't have to go crazy as maintainer.

Also thanks to Grygorii for reviewing and fixing stuff.

I hope we can switch a bunch of other drivers over to using
the banked IRQ infrastructure for v4.16.

Yours,
