[Sound-open-firmware] [PATCH 0/6] Add a vhost RPMsg API

[Guennadi Liakhovetski]

Linux supports RPMsg over VirtIO for "remote processor" /AMP use
cases. It can however also be used for virtualisation scenarios,
e.g. when using KVM to run Linux on both the host and the guests.
This patch set adds a wrapper API to facilitate writing vhost
drivers for such RPMsg-based solutions. The first use case is an
audio DSP virtualisation project, currently under development, ready
for review and submission, available at
https://github.com/thesofproject/linux/pull/1501/commits
A further patch for the ADSP vhost RPMsg driver will be sent
separately for review only since it cannot be merged without audio
patches being upstreamed first.

Thanks
Guennadi

  vhost: convert VHOST_VSOCK_SET_RUNNING to a generic ioctl
  vhost: (cosmetic) remove a superfluous variable initialisation
  rpmsg: move common structures and defines to headers
  rpmsg: update documentation
  vhost: add an rpmsg API
  rpmsg: add a device ID to also bind to the ADSP device
