+title: Qualcomm SMD Edge communication channel nodes
+
+maintainers:
+ - Bjorn Andersson <bjorn.andersson@linaro.org>
+
+description:
+ Qualcomm SMD subnode represents a remote subsystem or a remote processor of
+ some sort - or in SMD language an "edge". The name of the edges are not
+ important.
+
+ In turn, subnodes of the "edges" represent devices tied to SMD channels on
+ that "edge". The names of the devices are not important. The properties of
+ these nodes are defined by the individual bindings for the SMD devices.
+ See also Documentation/devicetree/bindings/soc/qcom/qcom,smd.yaml
