But the driver never enabled pm_runtime so it would never have powered- down the cs42l42 anyway. In fact, FILT+ can charge to operating voltage within 12.5 milliseconds of enabling HP or ADC. This time is already covered by the startup delay of the HP/ADC. The datasheet warning about FILT+ taking up to 1 second to charge only applies in the special cases that either the PLL is started or DETECT_MODE set to non-zero while both HP and ADC are off. The driver never does either of these. Removing idle_bias_on allows the Soundwire host controller to suspend if there isn't a snd_soc_jack handler registered.
