10   The Broadcom GPIO Controller IP can be configured prior to synthesis to
12   GPIO controller only supports edge, not level, triggering of interrupts.

33       The interrupt outputs from the controller. There is one GPIO interrupt
34       per GPIO bank. The number of interrupts listed depends on the number of
35       GPIO banks on the SoC. The interrupts must be ordered by bank, starting
