+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.
+- reg: register range associated the cluster clocks, offset must be 0
+ and the size have to be the whole size of the system-controller
+
+
+ap_syscon1: system-controller@6f8000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0x6f8000 0x1000>;
+
+ cpu_clk: clock-cpu@0 {
+ compatible = "marvell,ap806-cpu-clock";
+ clocks = <&ap_clk 0>, <&ap_clk 1>;
+ #clock-cells = <1>;
+ reg = <0x0 0x1000>;
