+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>;
+ };

+Rockchip SRAM for smp bringup:
+------------------------------
+
+Rockchip's smp-capable SoCs use the first part of the sram for the bringup
+of the cores. Once the core gets powered up it executes the code that is
+residing at the very beginning of the sram.
+
+Therefore a reserved section sub-node has to be added to the mmio-sram
+declaration.
+
+Required sub-node properties:
+- compatible : should be "rockchip,rk3066-smp-sram"
+
+The rest of the properties should follow the generic mmio-sram discription
+found in ../../misc/sram.txt
+
+Example:
+
+ sram: sram@10080000 {
+ compatible = "mmio-sram";
+ reg = <0x10080000 0x10000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ smp-sram@10080000 {
+ compatible = "rockchip,rk3066-smp-sram";
+ reg = <0x10080000 0x50>;
+ };
+ };
