[PATCHv5 09/10] arm: mvebu: add .dts file for Synology DS213j

+			poweroff at 12100 {
+				compatible = "synology,power-off";
+				reg = <0x12100 0x100>;
+				clocks = <&coreclk 0>;
+			};

So we have power off using the PIC.

+	poweroff_pin: poweroff-pin {
+		marvell,pins = "mpp4";
+		marvell,function = "gpio";
+	};

Do you know what this pin is used for?
