Optional properties:



Some PMUs are capable of behaving as an interrupt controller (mostly

to wake up a suspended PMU). In which case, they can have the

following properties:



- interrupt-controller: indicate that said PMU is an interrupt controller



- #interrupt-cells: must be identical to the that of the parent interrupt

  controller.



- interrupt-parent: a phandle indicating which interrupt controller

  this PMU signals interrupts to.



Example :

pmu_system_controller: system-controller@10040000 {

	compatible = "samsung,exynos5250-pmu", "syscon";

	reg = <0x10040000 0x5000>;

	interrupt-controller;

	#interrupt-cells = <3>;

	interrupt-parent = <&gic>;

	#clock-cells = <1>;

	clock-names = "clkout0", "clkout1", "clkout2", "clkout3",

			"clkout4", "clkout8", "clkout9";
