As I mentioned in the cover message, as a device part was used our own proprietary implementation. And there are no plans to upstream that part. > Thanks > > Liam > --------------------------------------------------------------------- > Intel Corporation (UK) Limited > Registered No. 1134945 (England) > Registered Office: Pipers Way, Swindon SN3 1RJ > VAT No: 860 2173 47 > > This e-mail and any attachments may contain confidential material for > the sole use of the intended recipient(s).

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.
