- interrupt-parent : phandle of the parent interrupt controller.
- interrupts : Interrupt specifier for the controllers interrupt.
- interrupt-controller : Mark the device node as an interrupt controller.
- #interrupt-cells : Should be 1. The first cell is the GPIO number.
- #interrupt-cells : Should be 2. The first cell defines the interrupt number.
The second cell bits[3:0] is used to specify trigger type as follows:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
