Subject: [PATCH 00/14] Add dedicated device tree node for RPM
 processor/subsystem

The Resource Power Manager (RPM) currently does not have a dedicated 
device tree node that represents the remoteproc/subsystem. The 
functionality exposed through the SMD/GLINK channels is described in 
top-level nodes of the device tree. This makes it hard to group other 
functionality provided by the RPM together in the device tree. This 
series adds a single top-level remoteproc-rpm/rpm-proc device tree node 
that groups all RPM functionality together.
