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 };
