Configuration properties for the qrtr MHI Transport.
|
|
This configuration is to instantiate a transport for
|
|
IPC Router protocol communication between APPS and
|
|
external modems.
|
|
|
|
properties:
|
|
compatible:
|
|
enum:
|
|
- qcom,qrtr-mhi
|
|
- qcom,qrtr-mhi-dev
|
|

qcom,dev-id:
|
|
$ref: '/schemas/types.yaml#/definitions/uint32'
|
|
maxItems: 1
|
|
description:
|
|
indicates the dev-id that this transport is for.
|
|
Should be passed into the qrtr core logic to determine
|
|
to match with the dev-id used by the mhi controller.
|
|
|
|
qcom,net-id:
|
|
$ref: '/schemas/types.yaml#/definitions/uint32'
|
|
maxItems: 1
|
|
description:
|
|
indicates what subnet this transport belongs to.
|
|
If the dev-id passed above matches the one passed into qrtr
|
|
logic by mhi core, then this net-id is passed into the qrtr
|
|
core logic to determin if forwarding is needed on this endpoint.
|
|
|
|
qcom,low-latency:
|
|
type: boolean
|
|
description:
|
|
indicates whether this transport receiving thread needs
|
|
to be set to realtime priority for enhanced performance.
