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>;

		};
