GPIOs that are wakeup capable have interrupt lines that are routed to
the always-on interrupt controller (PDC) in parallel to the pinctrl. The
interrupts listed here are the wake up lines corresponding to GPIOs.

In order to get any GPIO interrupts on my board, I needed to add the
summary IRQ first in this list. My reading of platform_get_irq is that
"interrupts-extended" is queried before "interrupts", so we
accidentally wire the summary IRQ to PDC 30. Given this, you can
probably remove the regular "interrupts" property.

Sure. Will fix that.
