Subject: [PATCH v3 0/5] soundwire: intel: add DAI callbacks

The existing mainline code is missing most of the DAI callbacks needed
for a functional implementation, and the existing ones need to be
modified to provide the relevant information to ASoC/SOF drivers.

As suggested by Vinod, these patches are shared first - with the risk
that they are separated from the actual DAI enablement, so reviewers
might wonder why they are needed in the first place.

For reference, the complete set of 90+ patches required for SoundWire
on Intel platforms is available here:

https://github.com/thesofproject/linux/pull/1692

Changes since v2:
Add missing kfree for stream name (feedback from Vinod)

changes since v1:
Fix string allocation (only feedback from Vinod)

Pierre-Louis Bossart (2):
  soundwire: intel: rename res field as link_res
  soundwire: intel: free all resources on hw_free()

Rander Wang (3):
  soundwire: intel: add prepare support in sdw dai driver
  soundwire: intel: add trigger support in sdw dai driver
  soundwire: intel: add sdw_stream_setup helper for .startup callback
