+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 onboard 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";
+ };
+ };
