Qualcomm Technologies, Inc. IPC Router MHI_DEV Transport



Required properties:

-compatible:		should be "qcom,ipc-router-mhi-dev-xprt".

-qcom,out-chan-id:	MHI Channel ID for the transmit path.

-qcom,in-chan-id:	MHI Channel ID for the receive path.

-qcom,xprt-remote:	string that defines the edge of the transport.

-qcom,xprt-linkid:	unique integer to identify the tier to which the link

			belongs to in the network and is used to avoid the

			routing loops while forwarding the broadcast messages.

-qcom,xprt-version:	unique version ID used by MHI transport header.



Example:

	qcom,ipc_router_external_ap_xprt {

		compatible = "qcom,ipc-router-mhi-dev-xprt";

	        qcom,out-chan-id = <34>;

		qcom,in-chan-id = <35>;

		qcom,xprt-remote = "external-ap";

		qcom,xprt-linkid = <2>;

		qcom,xprt-version = <1>;

	};
