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"; |
|
};
