+
+CPU control register allows various operations on CPUs, like resetting them
+independently.
+
+Required properties:
+- compatible: should be "marvell,berlin-cpu-ctrl"
+- reg: address and length of the register set
+
+Example:
+
+cpu-ctrl at f7dd0000 {
+	compatible = "marvell,berlin-cpu-ctrl";
+	reg = <0xf7dd0000 0x10000>;
+};
