    +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";
    + };
    + }
    +
