		Zodiac Inflight Innovations RAVE Supervisory Processor Watchdog Bindings

		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";
		};
		}
