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

Like that, we keep it consistent with the naming that was given in the commit that you mentioned in the commit description.
