Qualcomm Technologies, Inc. G-link bgcom Transport



Required properties:

-compatible : should be "qcom,glink-bgcom-xprt".

-label : the name of the subsystem this link connects to.



Optional properties:

-qcom,qos-config: Reference to the qos configuration elements.It depends on

		ramp-time.

-qcom,ramp-time: Worst case time in microseconds to transition to this power

		state. Power states are numbered by array index position.



Example:



	qcom,glink-bgcom-xprt-bg {

		compatible = "qcom,glink-bgcom-xprt";

		label = "bg";

		qcom,qos-config = <&glink_qos_bg>;

		qcom,ramp-time = <0x10>,

				     <0x20>,

				     <0x30>,

				     <0x40>;

	};



	glink_qos_bg: qcom,glink-qos-config-bg {

		compatible = "qcom,glink-qos-config";

		qcom,flow-info = <0x80 0x0>,

				 <0x70 0x1>,

				 <0x60 0x2>,

				 <0x50 0x3>;

		qcom,mtu-size = <0x800>;

		qcom,tput-stats-cycle = <0xa>;

	};
