+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 {
