Zodiac Inflight Innovations RAVE Supervisory Processor

RAVE Supervisory Processor communicates with SoC over UART. It is
expected that its Device Tree node is specified as a child of a node
corresponding to UART controller used for communication.

Required parent device properties:

• compatible: Should be one of:

  • “zii,rave-sp-niu”
  • “zii,rave-sp-mezz”
  • “zii,rave-sp-esb”
  • “zii,rave-sp-rdu1”
  • “zii,rave-sp-rdu2”

• current-speed: Should be set to baud rate SP device is using

RAVE SP consists of the following sub-devices:

Device Description

---

rave-sp-wdt : Watchdog
rave-sp-nvmem : Interface to onborad EEPROM
rave-sp-backlight : Display backlight
rave-sp-hwmon : Interface to onboard hardware sensors
rave-sp-leds : Interface to onboard LEDs
rave-sp-input : Interface to onboard power button

Example of usage:

rdu {
    compatible = "zii,rave-sp-rdu2";
    current-speed = <1000000>;

    watchdog {
        compatible = "zii,rave-sp-watchdog";
    };
};
