Texas Instruments - tlv320aic3x Codec module
The tlv320aic3x serial control bus communicates through I2C protocols
Required properties:
- compatible - "string" - One of:
"ti,tlv320aic3x" - Generic TLV320AIC3x device
"ti,tlv320aic33" - TLV320AIC33
"ti,tlv320aic3007" - TLV320AIC3007
"ti,tlv320aic3106" - TLV320AIC3106
- reg - <int> - 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.
- AVDD-supply, IOVDD-supply, DRVDD-supply, DVDD-supply : power supplies for the
device as covered in Documentation/devicetree/bindings/regulator/regulator.txt
Example:
tlv320aic3x: tlv320aic3x@1b {
compatible = "ti,tlv320aic3x";
reg = <0x1b>;
AVDD-supply = <&regulator>;
IOVDD-supply = <&regulator>;
DRVDD-supply = <&regulator>;
DVDD-supply = <&regulator>;
};
