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.
