Kernel-4.18.0-80.el8_tlv320aic32x4

Texas Instruments - tlv320aic32x4 Codec module

The tlv320aic32x4 serial control bus communicates through I2C protocols

Required properties:

  • compatible - “string” - One of:
    “ti,tlv320aic32x4” TLV320AIC3204
    “ti,tlv320aic32x6” TLV320AIC3206, TLV320AIC3256
  • reg: I2C slave address
  • supply-*: Required supply regulators are:
    “iov” - digital IO power supply
    “ldoin” - LDO power supply
    “dv” - Digital core power supply
    “av” - Analog core power supply
    If you supply ldoin, dv and av are optional. Otherwise they are required
    See regulator/regulator.txt for more information about the detailed binding
    format.

Optional properties:

  • reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
  • clocks/clock-names: Clock named ‘mclk’ for the master clock of the codec.
    See clock/clock-bindings.txt for information about the detailed format.
  • aic32x4-gpio-func - <array of 5 int>
    • Types are defined in include/sound/tlv320aic32x4.h

Example:

codec: tlv320aic32x4@18 {
compatible = “ti,tlv320aic32x4”;
reg = <0x18>;
clocks = <&clks 201>;
clock-names = “mclk”;
aic32x4-gpio-func= <
