[BUG][SDW][CML] clock stop prepare issue - Speaker cannot work after suspend/resume

[bardliao]

Canonical reported an issue that speaker can't work on CML + dual rt1308 laptop.
The issue happens only once so far.
The error kernel log is

rt1308 sdw:1:25d:1308:0: Clock Stop prepare failed for slave: -61
rt1308 sdw:1:25d:1308:0: pre-prepare failed:-61
intel-master sdw-master-1: prepare clock stop failed -61
intel-master sdw-master-1: cannot enable clock stop on suspend
...
rt1308 sdw:1:25d:1308:0: Unable to sync register 0xc030. -22
intel-master sdw-master-1: pm_runtime_get_sync failed in intel_startup, ret -22
intel-master sdw-master-1: ASoC: can't open DAI SDW1 Pin2: -22
SDW1-Playback: ASoC: BE open failed -22
SDW1-speakers: ASoC: failed to start some BEs -22

The issue is that somehow we didn't get ACK from codec and then cause clock stop prepare failed.
The question is that do we have a way to recover from no ack received?

[plbossart]

can we have a longer dmesg trace @bardliao ?

What we could do in this case is just to mark the device as not functional, suspend anyways and reset the bus on startup.

But that looks like a corner case for now.

@bardliao @plbossart It seems this issue can be reproduced with SDCA codec ALC1316 on TGL-U laptop device. Please check CI report 1118 on 2020-12-10 (UTC). Failed case: check-suspend-resume-with-playback-25.sh

@plbossart @bardliao Can we take this issue as a duplicate of #2621 ?
