Please note: this patch series depends on [3].

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.

Corresponding backend, implemented as a user-space application, can be
found at [2].
Through a quick glance, all look OK for merge (assuming that they
really work on your systems :)
Well, we have tested this at EPAM on Android/Linux, so this is it for now

Of course, it'd be great if anyone else can review, test and give
reviewed-by or tested-by tags.
I hope Juergen and Boris can review, at least Juergen had some comments
that I have addressed in v3
So I'll keep this floating for a
couple of days and merge to for-next branch after that.
Oh, this is great news! Thank you

thanks,

Takashi
