Qualcomm Technologies, Inc. IPC Router SMD Transport



Required properties:

-compatible:		should be "qcom,ipc_router_smd_xprt"

-qcom,ch-name:		the SMD channel name used by the SMD transport

-qcom,xprt-remote:	string that defines the edge of the transport (PIL Name)

-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 SMD transport header



Optional properties:

-qcom,fragmented-data:	Indicate the SMD transport supports fragmented data

-qcom,disable-pil-loading: Disable PIL Loading of the remote subsystem



Example:

	qcom,ipc_router_modem_xprt {

		compatible = "qcom,ipc_router_smd_xprt";

		qcom,ch-name = "IPCRTR";

		qcom,xprt-remote = "modem";

		qcom,xprt-linkid = <1>;

		qcom,xprt-version = <1>;

		qcom,fragmented-data;

		qcom,disable-pil-loading;

	};



	qcom,ipc_router_q6_xprt {

		compatible = "qcom,ipc_router_smd_xprt";

		qcom,ch-name = "IPCRTR";

		qcom,xprt-remote = "adsp";

		qcom,xprt-linkid = <1>;

		qcom,xprt-version = <1>;

		qcom,fragmented-data;

	};
