| * 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! |
