Subject: [PATCH v2 00/14] soundwire: Add a new SoundWire 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_v2

v1: https://lkml.org/lkml/2017/10/18/1030
RFC: https://lkml.org/lkml/2016/10/21/395

Changes in v2:
- move documentation into driver-api and do rst conversion
- fix documentation comments
- add SPDX-License-Identifier: (GPL-2.0 OR BSD-3-Clause) to all
  source files
- rework the transfer logic and paging logic as commented on v1
- remove dummy sysfs fns
- registration checks and fixes
- remove slave check for regamp as that turned superfluous
- remove depends SoundWire symbol
- make modalias api arg const
- use bitmap for tracking assigned
- add counter for report present tracking
todo: add the dt-bindings
