On BIAS STANDBY->OFF transition the current implementation sleeps 600ms on suspend in order to discharge the chip. The suspend is propagated from "snd_soc_suspend" call for all audio cards in a serial fashion, thus in case of boards like i.MX8DXL EVK which has 3 distinct WM8960 codecs the total cumulated sleep on suspend is 1.8 seconds. On the other hand the BIAS OFF->STANDBY transition happens asynchronously with regard to "snd_soc_resume" - the call is propagated from "soc_resume_deferred" which is just scheduled from "snd_soc_resume", each card having its own work scheduled to execute "soc_resume_deferred" call. The patch performs discharge completion on BIAS OFF->STANDBY transition so that the cumulated effect on suspend described above is avoided and discharge is completed in paralel in case of multiple WM8960 codecs on the board.
