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";
|
|
};
