Merge tag 'rpmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "remoteproc/rpmsg: new subsystem" from Arnd Bergmann:
"This new subsystem provides a common way to talk to secondary
processors on an SoC, e.g. a DSP, GPU or service processor, using
virtio as the transport. In the long run, it should replace a few
dozen vendor specific ways to do the same thing, which all never made
it into the upstream kernel. There is a broad agreement that rpmsg is
the way to go here and several vendors have started working on
replacing their own subsystems.
Two branches each add one virtio protocol number. Fortunately the
numbers were agreed upon in advance, so there are only context
changes.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>"
Fixed up trivial protocol number conflict due to the mentioned additions
next to each other.
