Qualcomm Technologies, Inc GLINK BGCOM transport (glink_bgcom_xprt) binding



This binding describes the Qualcomm Technologies, Inc glink bgcom transport

driver, a bgcom-spi based communication channel for sending data between the

various subsystems in Qualcomm Technologies, Inc platforms.



- compatible:

	Usage: required

	Value type: <stringlist>

	Definition: must be "qcom,glink-bgcom-xprt"



- label:

	Usage: required

	Value type: <stringlist>

	Definition: must be "bg"



= EXAMPLE



The following example reprsents a glink_bgcom node.



	qcom,glink-bgcom-xprt-bg {

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

		label = "bg";

	};
