[alsa-devel] [PATCH 00/14] soundwire: Add a new SoundWire subsystem

So today we celebrate Diwali, the festival of lights in this part of
the world. On this occasion I would like to add a new Linux subsystem.

This patch series adds a new SoundWire subsystem which implements a
new MIPI bus protocol 'SoundWire'.

The SoundWire protocol is a robust, scalable, low complexity, low
power, low latency, two-pin (clock and data) multi-drop bus that
allows for the transfer of multiple audio streams and embedded
control/commands.  SoundWire provides synchronization capabilities and
supports both PCM and PDM, multichannel data, isochronous and
asynchronous modes.

This series adds SoundWire Bus, IO transfers, DisCo (Discovery and
Configuration) sysfs interface, regmap and Documentation summary

This patch series is also available on
git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire.git
topic/patch_v1

This is first version of the patch which incorporates lots of changes
based on the RFC series posted last year
