Hi Amadeusz,
Yes, the original version I tried the implementation on audio machine driver, but one person gave me an idea for this dmic.c Do you think it is appropriate on dmic.c? If it isn't, I will add kcontrol into audio machine driver. thanks

Refer to this one as an example, commit 3cfbf07c6d27 ("ASoC: qcom: sc7180: Modify machine driver for 2mic")

I'm very suspicious of this patchset. As it is you add kcontrol which won't take effect on most platforms making use of DMIC. It feels to me that it is something you want to handle on machine driver side instead.
