1	Marvell Kirkwood Platforms Device Tree Bindings
2	-----------------------------------------------
3	
4	Boards with a SoC of the Marvell Kirkwood
5	shall have the following property:
6	
7	Required root node property:
8	
9	compatible: must contain "marvell,kirkwood";
10	
11	In order to support the kirkwood cpufreq driver, there must be a node
12	cpus/cpu@0 with three clocks, "cpu_clk", "ddrclk" and "powersave",
13	where the "powersave" clock is a gating clock used to switch the CPU
14	between the "cpu_clk" and the "ddrclk".
15	
16	Example:
17	
18		cpus {
19			#address-cells = <1>;
20			#size-cells = <0>;
21	
22			cpu@0 {
23			      device_type = "cpu";
24			      compatible = "marvell,sheeva-88SV131";
25			      clocks = <&core_clk 1>, <&core_clk 3>, <&gate_clk 11>;
26			      clock-names = "cpu_clk", "ddrclk", "powersave";
27			};
