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";
