0001 Marvell Kirkwood Platforms Device Tree Bindings
0002 -----------------------------------------------
0003
0004 Boards with a SoC of the Marvell Kirkwood
0005 shall have the following property:
0006
0007 Required root node property:
0008
0009 compatible: must contain "marvell,kirkwood";
0010
0011 In order to support the kirkwood cpufreq driver, there must be a node
0012 cpus/cpu@0 with three clocks, "cpu_clk", "ddrclk" and "powersave",
0013 where the "powersave" clock is a gating clock used to switch the CPU
0014 between the "cpu_clk" and the "ddrclk".
0015
0016 Example:
0017
0018         cpus {
0019                 #address-cells = <1>;
0020                 #size-cells = <0>;
0021
0022                 cpu@0 {
0023                       device_type = "cpu";
0024                       compatible = "marvell,sheeva-88SV131";
0025                       clocks = <&core_clk 1>, <&core_clk 3>, <&gate_clk 11>;
0026                       clock-names = "cpu_clk", "ddrclk", "powersave";
0027                 };
