-Lantiq WTD watchdog binding
-============================
-
-This describes the binding of the Lantiq watchdog driver.

--------------------------------------------------------------------------------
-Required properties:
-- compatible		: Should be one of

-				"lantiq,xrx100-wdt"
-				"lantiq,xrx200-wdt", "lantiq,xrx100-wdt"
