+* 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@fffffd40 {
+ compatible = "atmel,at91sam-wdt";
+ reg = <0xfffffd40 0x10>;
+ status = "okay";
+ };
