The number of GPIOs the controller *provides* is to be determined by the compatible-string. ngpios is used to restrict the number of lines *used* or *routed* from the number *available*. (I hope that is what the code does as well.) Such as if 12 GPIOs are used of the 32 available on 32bits in a register. Update this description to say what it really means.
