- gpio-reset - gpio pin number used for codec reset
- ai3x-gpio-func - <array of 2 int> - AIC3X_GPIO1 & AIC3X_GPIO2 Functionality
- ai3x-micbias-vg - MicBias Voltage required.
1 - MICBIAS output is powered to 2.0V,
2 - MICBIAS output is powered to 2.5V,
3 - MICBIAS output is connected to AVDD,
If this node is not mentioned or if the value is incorrect, then MicBias
is powered down.
