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:
|
|
