Subject: [PATCH v5 00/15] 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

v4: https://lkml.org/lkml/2017/12/1/205
v3: https://lkml.org/lkml/2017/11/30/160
v2: https://lkml.org/lkml/2017/11/10/216
v1: https://lkml.org/lkml/2017/10/18/1030
RFC: https://lkml.org/lkml/2016/10/21/395
Changes in v5:
- Address comments by Pierre
- add reference to mid.mipi.org in documentation
- add group and master device number and don't use those for enumeration
- fix unused calls in disco code and also remove superfluous initialization
- remove sdw_transfer apis slave arg, make enum values integer and not
bitmaps
- clarify the sdw_program_device_num loop and fix interrupt handling
Changes in v4:
- Remove text licenses and add SPDX tags only with C99 style comments
- make bus_type code as GPL v2.0 only
Changes in v3:
- Update the kernel-doc styles and fix included headers for files
- handle dev_pm_domain_attach() for defered probe
- remove OF placeholders
- change regmap license to GPLv2 only
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
