Looks pretty good to me.  A few comments below, but I'm okay with this
one being picked up (Ralf, or if you prefer then I can merge it via my
tree) as long as you follow it up with a fixup patch.

Are there any configuration parameters for these irq inputs?  Edge vs.
Level? Active high or active low?  If so, then you'll probably want to
have a flags cell.

Also, how are the irqs typically documented in the hardware reference
manual?  Are they documented a irqs 0-63 in bank 1 and 0-63 in bank 2?
Or are is a flat 0-127 number range?  If it is the later, then you may
want to consider just using a single cell to specify the irq number,
and handle the bank calculation in the irq driver.

Since you're choosing arbitrary values here anyway, it's convenient to
follow the lead of include/linux/irq.h and using 1->edge rising,
2->edge falling, 4->level high, 8->level low.  In the past every irq
controller kind of did it's own thing, but that's not very scalable.
