If it is a board specific requirement, then would it make sense to have it in dai_link as per Peter Ujfaulsi's RFC [1].
Possibly for your case - the case this was originally written for was rather different, the CODEC has issues which mean it always needs to skip the delay so having to specify this for every single board is going to be repetitive.
In general, how this kind of situation is handled?
Usually by keeping the clocks available.
That does not seem to be possible here :(
The codec takes the clock from modem. The codec doesn't have control over it. The voice call termination kills the clock and the DAPM power down produces noticeable artifacts.
Since this is board property, machine driver should tell DAPM to power down immediately for this DAI alone. That of course allows us to reap benefits of DAPM not power cycling codec during close/open.
