18Optional properties:
19
20- gpio-reset - gpio pin number used for codec reset
21- ai3x-gpio-func - <array of 2 int> - AIC3X_GPIO1 & AIC3X_GPIO2 Functionality
22				    - Not supported on tlv320aic3104
23- ai3x-micbias-vg - MicBias Voltage required.
24	1 - MICBIAS output is powered to 2.0V,
25	2 - MICBIAS output is powered to 2.5V,
26	3 - MICBIAS output is connected to AVDD,
27	If this node is not mentioned or if the value is incorrect, then MicBias
28	is powered down.
