			 * 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!
