+Lantiq WTD watchdog binding
+============================
+
+This describes the binding of the Lantiq watchdog driver.
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible		: Should be one of
+				"lantiq,wdt"
+				"lantiq,wdt-xrx100"
+				"lantiq,wdt-falcon"
+
+Optional properties:
+- regmap		: A phandle to the RCU syscon
+- offset-status		: Offset of the reset cause register
+- mask-status		: Mask of the reset cause register value
+
+
+-------------------------------------------------------------------------------
+Example for the watchdog on the xRX200 SoCs:
+		watchdog@803F0 {
+			compatible = "lantiq,wdt-xrx200", "lantiq,wdt-xrx100";
+			reg = <0x803F0 0x10>;
+
+			regmap = <&rcu0>;
+			offset-status = <0x14>;
+			mask-status = <0x80000000>;
+		};
