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";

		};

	}
