I just tried merging both. The problem i noticed is that the PGIO interrupts are independable and each GPIO will generate an event, which is wrong. Assume the switch state change from position 2 to 1 it will actually generate lots of interrupts: e.g. 2, 1, 2, 1. Depending from the order of such interrupts the last event shows a possible wrong position. This can only be avoided if each GPIO interrupt starts the same state checking routine. Thus reading the GPIO pin state and report just one event. Some ideas to still merge those drivers?
