Qualcomm Technologies, Inc. IPC Router G-Link Transport



Required properties:

-compatible:		should be "qcom,ipc_router_glink_xprt"

-qcom,ch-name:		the G-Link channel name used by the G-Link transport

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

-qcom,glink-xprt:	string that describes the underlying physical 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 G-Link transport header



Optional properties:

-qcom,fragmented-data:	Boolean property to indicate that G-Link transport

			supports fragmented data

-qcom,disable-pil-loading: Boolean property to disable PIL Loading of the

			   remote subsystem



Example:

	qcom,ipc_router_modem_xprt {

		compatible = "qcom,ipc_router_glink_xprt";

		qcom,ch-name = "IPCRTR";

		qcom,xprt-remote = "mpss";

		qcom,glink-xprt = "smem";

		qcom,xprt-linkid = <1>;

		qcom,xprt-version = <1>;

		qcom,fragmented-data;

		qcom,disable-pil-loading;

	};



	qcom,ipc_router_q6_xprt {

		compatible = "qcom,ipc_router_glink_xprt";

		qcom,ch-name = "IPCRTR";

		qcom,xprt-remote = "lpass";

		qcom,glink-xprt = "smem";

		qcom,xprt-linkid = <1>;

		qcom,xprt-version = <1>;

		qcom,fragmented-data;

	};
