54 | * The GPIO IP block is designed for 3 banks of GPIOs. | |
55 | * Each bank has a GPIO interrupt for itself. | |
56 | * There is an overall "any bank" interrupt. | |
57 | * In order, these are GIC interrupts 17, 18, 19, 20. | |
58 | * Since the BCM2835 only has 2 banks, the 2nd bank | |
59 | * interrupt output appears to be mirrored onto the | |
60 | * 3rd bank's interrupt signal. | |
61 | * So, a bank0 interrupt shows up on 17, 20, and | |
62 | * a bank1 interrupt shows up on 18, 19, 20! | |
