[alsa-devel] [PATCH v2 0/5] soundwire: update ASoC interfaces

We need new fields in existing structures to
a) deal with race conditions on codec probe/enumeration
b) allow for multi-step ACPI scan/probe/startup on Intel plaforms

To avoid conflicts between ASoC and Soundwire trees, these 4 patches
are provided out-of-order, before the functionality enabled in these
header files is added in follow-up patch series which can be applied
separately in the ASoC and Soundwire trees (of course after Vinod and
Mark sync-up so that these patches are present in both trees).

Changes since v1 (no feedback received since October 23)
additional initialization_complete utility to help codec drivers with
their resume operation, waiting for the enumeration to complete is not
always enough.

Pierre-Louis Bossart (4):
  soundwire: sdw_slave: add new fields to track probe status
  soundwire: add enumeration_complete structure
  soundwire: add initialization_complete definition
  soundwire: intel: update interfaces between ASoC and SoundWire

  soundwire: intel: update stream callbacks for hwparams/free stream
    operations
