Yes, you are correct, I should keep the string format consistent with the commit I mentioned in descriptions to avoid confusion. I will submit the next. Thanks. Regards.

Having two DMICs, a front DMIC and a Rear DMIC, but only host audio input AUX port0 is used for these two Dmics. A "dmic-gpios" property is used for a mixer control to switch the dmic signal source between the Front and Rear Dmic.
