This patch series adds support for Xen [1] para-virtualized
sound frontend driver. It implements the protocol from
include/xen/interface/io/sndif.h with the following limitations:
- mute/unmute is not supported
- get/set volume is not supported
Volume control is not supported for the reason that most of the
use-cases (at the moment) are based on scenarious where
unprivileged OS (e.g. Android, AGL etc) use software mixers.

Both capture and playback are supported.

Thank you,

As a quick glance of your first patch, it's apparently based on your local working branch.
sorry about that, I based the changes on v4.13-rc3 kernel sources
I'd like you to post patchset again, which were rebased on current upstream[1], so that code reviewers can do their work.
sure, will do that now
