+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@803f0 {
+ compatible = "lantiq,xrx200-wdt", "lantiq,xrx100-wdt";
+ reg = <0x803f0 0x10>;
+
+ lantiq,rcu = <&rcu0>;
+ };
