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"; }; };
