-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";
- };
- }
