[PATCH v4 00/13] soundwire: Add stream support

[Vinod Koul <vinod.koul@intel.com>]

This series adds support in SoundWire subsystem for:
 - Documentation for stream support
 - stream management
 - data port management
 - DAI ops in cadence and Intel drivers
 - ASoC API to propagate SDW stream

Updates in v4:
 - Add more comments for sdw_release_master_stream()
 - Make sure ports are freed upon sdw_stream_remove_slave()
 - Clarify snd_soc_dai_set_sdw_stream() and setting of NULL upon release.

Updates in v3:
 - Remove stream state transition checks and redefine stream states
 - Update bansk switch routines
 - Other nitpicks pointed out by Pierre.

Updates in v2:
  - Make ASoC API inlined
  - Make stream states as states and not action
  - Update the direction enum
  - Fix some typos and comment updates
