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.
