+=========================================================
+Secondary CPU enable-method "nuvoton,npcm7xx-smp" binding
+=========================================================
+
+To apply to all CPUs, a single "nuvoton,npcm7xx-smp" enable method should be
+defined in the "cpus" node.
+
+Enable method name: "nuvoton,npcm7xx-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,npcm7xx-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>;
+ };
+ };
