+* Atmel's Watchdog Timer Controller
+
+Required properties:
+- compatible : should be "atmel,at91sam-wdt"
+- reg : base physical address of the controller and length of memory mapped
+	region.
+
+Example:
+
+	watchdog at fffffd40 {
+		compatible = "atmel,at91sam-wdt";
+		reg = <0xfffffd40 0x10>;
+		status = "okay";
+	};
