|
|
|
|
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
|
