+Qualcomm Technologies, Inc. GLINK Probe
+
+This binding describes the GLINK Probe driver, a device
+that initializes the GLINK edge pairs within the system.
+
+- compatible :
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "qcom,glink"
+
+= SUBNODES
+The GLINK probe node must contain subnodes that describes the
+edge-pairs. See qcom,glink.txt for details on how to describe them.
+
+In addition to the properties in qcom,glink.txt, The GLINK Probe driver
+requires the qcom,glink-label and transport type to be specified in the
+subnodes.
+
+- transport :
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "smem", "spss", or "spi"
+
+- qcom,glink-label :
+	Usage: required
+	Value type: <stringlist>
+	Definition: specifies the identifier of the remote proc of this edge.
+
+= GLINK_SSR
+The GLINK probe driver also initializes the GLINK_SSR channel for the edges
+that it brings up. The channel should be specified as a subnode to each edge. In
+addition to the properties in qcom,glink.txt to specify a channel device node,
+the qcom,notify-edges property must be defined.
+
+- qcom,notify-edges :
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: list of phandles that specify the subsystems this glink edge
+		    needs to receive ssr notifications about.
+
