Looking again at this, the driver doesn't expose any new interrupts.
These 3 interrupts are simply passed on by the gpio chip's to_irq()
callback. The flags in the example depend entirely on the interrupt
parent, in this case the PDC irq driver in patch 2, so they don't need
documenting here.

Cheers
