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";
    };
}
