[alsa-devel] [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:
