The existing mainline code for SoundWire does not handle critical race conditions, and does not have any support for pm_runtime suspend or clock-stop modes needed for e.g. jack detection or external VAD.
As suggested by Vinod, these patches for the bus are shared first - with the risk that they are separated from their actual use in Intel drivers, 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
These patches are not Intel-specific and are likely required for e.g. Qualcomm-based implementations.
All the patches in this series were generated during the joint Intel-Realtek validation effort on Intel reference designs and form-factor devices. The support for the initialization_complete signaling is already available in the Realtek codecs drivers merged in the ASoC tree (rt700, rt711, rt1308, rt715)
Applied all, thanks
Thanks Vinod, I'll now prepare the update for the transition away from platform devices (minor update needed on the RFC already reviewed by Greg).
