Jean-Christophe Dubois f1f7e4bf76 i.MX: add support for lower and upper interrupt in GPIO. ... The i.MX6 GPIO device supports 2 interrupts instead of one. * 1 for the lower 16 GPIOs. * 1 for the upper 16 GPIOs. i.MX31 and i.MX25 only support 1 interrupt for the 32 GPIOs. So we add a property to turn the behavior on when required.
