-============================
-
-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>;
