+Lantiq WTD watchdog binding
+============================
+
+This describes the binding of the Lantiq watchdog driver.
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible		: Should be one of
+				"lantiq,wdt"
+				"lantiq,xrx100-wdt"
+				"lantiq,xrx200-wdt", "lantiq,xrx100-wdt"
+				"lantiq,falcon-wdt"
+- reg			: Address of the watchdog block
+- lantiq,rcu		: A phandle to the RCU syscon (required for
+			  "lantiq,falcon-wdt" and "lantiq,xrx100-wdt")
+
+-------------------------------------------------------------------------------
+Example for the watchdog on the xRX200 SoCs:
+		watchdog at 803f0 {
+			compatible = "lantiq,xrx200-wdt", "lantiq,xrx100-wdt";
+			reg = <0x803f0 0x10>;
+
+			lantiq,rcu = <&rcu0>;
+		};
