     23Optional properties:
     24
     25- reset-gpios - GPIO specification for the active low RESET input.
     26- ai31xx-micbias-vg - MicBias Voltage setting
     27        1 or MICBIAS_2_0V - MICBIAS output is powered to 2.0V
     28        2 or MICBIAS_2_5V - MICBIAS output is powered to 2.5V
     29        3 or MICBIAS_AVDD - MICBIAS output is connected to AVDD
     30	If this node is not mentioned or if the value is unknown, then
     31	micbias	is set to 2.0V.
     32- ai31xx-ocmv - output common-mode voltage setting

     42CODEC output pins:
     43  * HPL
     44  * HPR
     45  * SPL, devices with stereo speaker amp
     46  * SPR, devices with stereo speaker amp
     47  * SPK, devices with mono speaker amp
     48  * MICBIAS
     49
     50CODEC input pins:
     51  * MIC1LP, devices with ADC
