    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                 };
