-RAVE SP watchdog device is a "MFD cell" device corresponding to
-watchdog functionality of RAVE Supervisory Processor. It is expected
-that its Device Tree node is specified as a child of the node
-corresponding to the parent RAVE SP device (as documented in
-Documentation/devicetree/bindings/mfd/zii,rave-sp.txt)
-
-Required properties:
-
-- compatible: Depending on wire protocol implemented by RAVE SP
-  firmware, should be one of:
-	- "zii,rave-sp-watchdog"
-	- "zii,rave-sp-watchdog-legacy"
-
-Optional properties:
-
-- wdt-timeout:	Two byte nvmem cell specified as per
-		Documentation/devicetree/bindings/nvmem/nvmem.txt
-
-Example:
-
-	rave-sp {
-		compatible = "zii,rave-sp-rdu1";
-		current-speed = <38400>;
-
-		eeprom {
-			wdt_timeout: wdt-timeout@8E {
-				reg = <0x8E 2>;
-			};
-		};
-
-		watchdog {
-			compatible = "zii,rave-sp-watchdog";
-			nvmem-cells = <&wdt_timeout>;
-			nvmem-cell-names = "wdt-timeout";
-		};
-	}
