+Cluster clocks:
+---------------
+
+Device Tree Clock bindings for cluster clock of AP806 Marvell. Each
+cluster contain up to 2 CPUs running at the same frequency.
+
+Required properties:
+- compatible: must be  "marvell,ap806-cpu-clock";
+- #clock-cells : should be set to 1.
+- clocks : shall be the input parents clock phandle for the clock.
+
+Optional property:
+ - reg: register range associated the cluser clocks
+
+ap_syscon1: system-controller@6f8000 {
+	compatible = "syscon", "simple-mfd";
+	reg = <0x6f8000 0x1000>;

+	cpu_clk: clock-cpu {
+		compatible = "marvell,ap806-cpu-clock";
