+Marvell Kirkwood Platforms Device Tree Bindings
+-----------------------------------------------
+
+Boards with a SoC of the Marvell Kirkwood
+shall have the following property:
+
+Required root node property:
+
+compatible: must contain "marvell,kirkwood";
+
+In order to support the kirkwood cpufreq driver, there must be a node
+cpus/cpu@0 with three clocks, "cpu_clk", "ddrclk" and "powersave",
+where the "powersave" clock is a gating clock used to switch the CPU
+between the "cpu_clk" and the "ddrclk".
+
+Example:
+
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu@0 {
+ device_type = "cpu";
+ compatible = "marvell,sheeva-88SV131";
+ clocks = <&core_clk 1>, <&core_clk 3>, <&gate_clk 11>;
+ clock-names = "cpu_clk", "ddrclk", "powersave";
+ };
