I tried to update to this series on my 6.4-rc5 branch for the X13s and
the above changes appear to lead to breakages again.
Specifically, with the updated clk stop flag (simple_clk_stop_capable) I
see:
[ 14.789533] wcd9380-codec sdw:0:0217:010d:00:3: Slave 1 state check1: UNATTACHED, status was 1
[ 14.789717] qcom-soundwire 3330000.soundwire-controller: qcom_swrm_irq_handler: SWR bus clsh detected
[ 14.796164] wcd9380-codec sdw:0:0217:010d:00:3: Slave 1 state check1: UNATTACHED, status was 1
and without the runtime pm patch that you dropped in v2 I get
intermittent (e.g. twice in five boots):
[ 11.527301] snd-sc8280xp sound: ASoC: adding FE link failed
[ 11.527409] snd-sc8280xp sound: ASoC: topology: could not load header: -517
[ 11.527557] qcom-apm gprsvc:service:2:1: tplg component load failed-517
[ 11.527640] qcom-apm gprsvc:service:2:1: ASoC: error at snd_soc_component_probe on gprsvc:service:2:1: -22
[ 11.528079] snd-sc8280xp sound: ASoC: failed to instantiate card -22
[ 11.533388] snd-sc8280xp: probe of sound failed with error -22
Again, this was with 6.4-rc5, but these problems are likely still there
also with linux-next.
