Currently, stream is handled at the dai level. But we have to handle
stream at the dailink level in the multi-cpu dailink usage.

changes in v2:
 - Add kernel doc
 - Use single line trace log

Pierre-Louis Bossart (5):
  soundwire: intel: implement get_sdw_stream() operations
  soundwire: stream: add helper to startup/shutdown streams
  soundwire: intel: remove stream allocation/free
  soundwire: cadence: allocate/free dma_data in set_sdw_stream
  soundwire: intel: don't free dma_data in DAI shutdown
