In cases where more than two DMICs are used, we need to time-multiplex these DMICs. Therefore, we need to dynamically switch the modes of these DMICs based on the actual usage scenarios. ---- DMIC1 AU_VIN0 --- ---- DMIC2 AU_VIN2 --- ----DMIC3 When we want to use DMIC1/2, configure it to one-wire mode. When we want to use DMIC1/3, configure it to two-wire mode.
