1Marvell Kirkwood Platforms Device Tree Bindings 2----------------------------------------------- 3 4Boards with a SoC of the Marvell Kirkwood 5shall have the following property: 6 7Required root node property: 8 9compatible: must contain "marvell,kirkwood"; 10 11In order to support the kirkwood cpufreq driver, there must be a node 12cpus/cpu@0 with three clocks, "cpu_clk", "ddrclk" and "powersave", 13where the "powersave" clock is a gating clock used to switch the CPU 14between the "cpu_clk" and the "ddrclk". 15 16Example: 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 };
