Texas Instruments - tlv320aic3x Codec module

The tlv320aic3x serial control bus communicates through I2C protocols

Required properties:

  • compatible - “string” - “ti,tlv320aic3x”
  • reg - - I2C slave address

Optional properties:

  • 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.

Example:

tlv320aic3x: tlv320aic3x@1b {
compatible = “ti,tlv320aic3x”;
reg = <0x1b>;
};
