- clocks : list of phandles and specifiers to all input clocks listed in
clock-names property.
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";
