+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: Should be "zii,rave-sp-watchdog"
+
+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 {
+ compatible = "zii,pic-main-eeprom";
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ wdt_timeout: wdt-timeout@8E {
+ reg = <0x8E 2>;
+ };
+ };
+
+ watchdog {
+ compatible = "zii,rave-sp-watchdog";
+ nvmem-cells = <&wdt_timeout>;
+ nvmem-cell-names = "wdt-timeout";
+ };
+ }
