/*
* The GPIO IP block is designed for 3 banks of GPIOs.
* Each bank has a GPIO interrupt for itself.
* There is an overall "any bank" interrupt.
* In order, these are GIC interrupts 17, 18, 19, 20.
* Since the BCM2835 only has 2 banks, the 2nd bank
* interrupt output appears to be mirrored onto the
* 3rd bank's interrupt signal.
* So, a bank0 interrupt shows up on 17, 20, and
* a bank1 interrupt shows up on 18, 19, 20!
