| 2 | |
| 3 | RAVE Supervisory Processor communicates with SoC over UART. It is |
| 4 | expected that its Device Tree node is specified as a child of a node |
| 5 | corresponding to UART controller used for communication. |
| 6 | |
| 7 | Required parent device properties: |
| 8 | |
| 9 | - compatible: Should be one of: |
| 10 | - "zii,rave-sp-niu" |
| 11 | - "zii,rave-sp-mezz" |
| 12 | - "zii,rave-sp-esb" |
| 13 | - "zii,rave-sp-rdu1" |
| 14 | - "zii,rave-sp-rdu2" |
| 15 | |
| 16 | - current-speed: Should be set to baud rate SP device is using |
| 17 | |
| 18 | RAVE SP consists of the following sub-devices: |
| 19 | |
| 20 | Device Description |
| 21 | ------ ----------- |
| 22 | rave-sp-wdt : Watchdog |
| 23 | rave-sp-nvmem : Interface to onboard EEPROM |
| 24 | rave-sp-backlight : Display backlight |
| 25 | rave-sp-hwmon : Interface to onboard hardware sensors |
| 26 | rave-sp-leds : Interface to onboard LEDs |
| 27 | rave-sp-input : Interface to onboard power button |
| 28 | |
| 29 | Example of usage: |
| 30 | |
| 31 | rdu { |
| 32 | compatible = "zii,rave-sp-rdu2"; |
| 33 | current-speed = <1000000>; |
| 34 | |
| 35 | watchdog { |
| 36 | compatible = "zii,rave-sp-watchdog"; |
| 37 | }; |
| 38 | }; |
