Rockchip power-management-unit:
-------------------------------
The pmu is used to turn off and on different power domains of the SoCs
This includes the power to the CPU cores.
Required node properties:
- compatible value : = "rockchip,rk3066-pmu";
- reg : physical base address and the size of the registers window
Example:
pmu@20004000 {
compatible = "rockchip,rk3066-pmu";
reg = <0x20004000 0x100>;
};
