+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";
