+=========================================================
+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>;
+		};
+	};
