    @kv2019i, do you recall what we should or should not do with this?

    @ujfalusi This was found when comparing HDA programming between snd-hda-intel and SOF. Specifically this commit:

        ALSA: hda - set intel audio clock to a proper value
    

    Original patch done to fix https://bugzilla.kernel.org/show_bug.cgi?id=188411 .

    Starting point should be we do same exact programming (including any bug/workarounds) in SOF, but OTOH, this has been open for 4 years and nobody has complained, so maybe this is really not needed (read: in platforms SOF support, MLCAP is always set up correctly).
