=========================================================
Secondary CPU enable-method "nuvoton,npcm750-smp" binding
=========================================================
To apply to all CPUs, a single "nuvoton,npcm750-smp" enable method should be
defined in the "cpus" node.
Enable method name: "nuvoton,npcm750-smp"
Compatible machines: "nuvoton,npcm750"
Compatible CPUs: "arm,cortex-a9"
Related properties: (none)
Note:
This enable method needs valid nodes compatible with "arm,cortex-a9-scu" and
"nuvoton,npcm750-gcr".
Example:
cpus {
#address-cells = <1>;
#size-cells = <0>;
enable-method = "nuvoton,npcm750-smp";
cpu@0 {
device_type = "cpu";
compatible = "arm,cortex-a9";
clocks = <&clk NPCM7XX_CLK_CPU>;
clock-names = "clk_cpu";
reg = <0>;
next-level-cache = <&L2>;
};
cpu@1 {
device_type = "cpu";
compatible = "arm,cortex-a9";
clocks = <&clk NPCM7XX_CLK_CPU>;
clock-names = "clk_cpu";
reg = <1>;
next-level-cache = <&L2>;
};
};
