@ -24,10 +24,36 @@ Optional properties:
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
CODEC output pins:
* LLOUT
* RLOUT
* MONO_LOUT
* HPLOUT
* HPROUT
* HPLCOM
* HPRCOM
CODEC input pins:
* MIC3L
* MIC3R
* LINE1L
* LINE2L
* LINE1R
* LINE2R
The pins can be used in referring sound node's audio-routing property.
Example:
tlv320aic3x: tlv320aic3x@1b {
compatible = "ti,tlv320aic3x";
reg = <0x1b>;
AVDD-supply = <&regulator>;
IOVDD-supply = <&regulator>;
DRVDD-supply = <&regulator>;
DVDD-supply = <&regulator>;
