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