I think I should add more like an example,
description: dmic-gpios optional prop for switching between two DMICs.
Ex, the GPIO can control a MUX HW component to
select dmic clk and data form a Front or Rear dmic.
Do you agree with that or have other suggestions? If do, I will send
the v3 patch for you to check, thanks

Yes, you are right, I will change it to
dmic-gpios = <&pio 23 GPIO_ACTIVE_HIGH>;
