+Actions Semi Owl Smart Power System (SPS)
+
+Required properties:
+- compatible          :  "actions,s500-sps" for S500
+- reg                 :  Offset and length of the register set for the device.
+- #power-domain-cells :  Must be 1.
+                         See macros in:
+                          include/dt-bindings/power/owl-s500-powergate.h for S500
+
+
+Example:
+
+               sps: power-controller@b01b0100 {
+                       compatible = "actions,s500-sps";
+                       reg = <0xb01b0100 0x100>;
+                       #power-domain-cells = <1>;
+               };
