QTI QRTR MHI transport binding
- compatible:
Usage: required
Value type: <stringlist>
Definition: must be "qcom,qrtr-mhi"
"qcom,qrtr-mhi-dev"
- qcom,dev-id:
Usage: optional
Value type: <u32>
Definition: 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:
Usage: optional
Value type: <u32>
Definition: 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:
Usage: optional
Value type: <bool>
Definition: indicates whether this transport receiving thread needs to
be set to realtime priority for enhanced performance.
= EXAMPLE
The following example represents the qrtr mhi transport node on a device
configured as a pcie endpoint and needs to forward data from the host to a
slpi co-processor.
mhi_qrtr_cnss {
compatible = "qcom,qrtr-mhi";
qcom,dev-id = <0x1103>;
qcom,net-id = <0>;
qcom,low-latency;
};
