The PINT on has 8 interrupts, but this is device dependent. Up to 32 could be supported. The order is also device dependent. The interrupts on PINT are merely mapped onto the main interrupt controller. I tried to keep the wording in the binding generic so it could support the PINT on different devices. I'll update the text with some more details. regards, Joachim Eastwood
