4The sram of pmu is used to store the function of resume from maskrom(the 1st
5level loader). This is a common use of the "pmu-sram" because it keeps power
6even in low power states in the system.

8Required node properties:
9- compatible : should be "rockchip,rk3288-pmu-sram"
10- reg : physical base address and the size of the registers window

12Example:
13 sram@ff720000 {
14 compatible = "rockchip,rk3288-pmu-sram", "mmio-sram";
15 reg = <0xff720000 0x1000>;
