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.
As a device part was used OpenSynergy proprietary implementation.
v5 changes:
- Fixed another bunch of sparse warnings
(replaced virtio_cread() -> virtio_cread_le()), no functional changes.
(Sorry, I didn't know how to run sparse locally, now everything should be fixed)
