7 title: Qualcomm SMD Edge communication channel nodes
10   - Bjorn Andersson <bjorn.andersson@linaro.org>
13   Qualcomm SMD subnode represents a remote subsystem or a remote processor of
14   some sort - or in SMD language an "edge". The name of the edges are not
17   In turn, subnodes of the "edges" represent devices tied to SMD channels on
18   that "edge". The names of the devices are not important. The properties of
19   these nodes are defined by the individual bindings for the SMD devices.
