This series implements a driver part of the virtio sound device
specification v8 [1].
The driver supports PCM playback and capture substreams, jack and
channel map controls. A message-based transport is used to write/read
PCM frames to/from a device.
The series is based (and was actually tested) on Linus's master
branch [2], on top of
commit 1e2a199f6ccd ("Merge tag 'spi-fix-v5.11-rc4' of ...")
As a device part was used OpenSynergy proprietary implementation.
Any comments are very welcome.
