    Subject[PATCH v4 00/15] soundwire: Add a new SoundWire subsystem
    Date
    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_v4

    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 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
