- 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= <
- 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */
- 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */
- 0x04 /* MFP3 AIC32X4_MFP3_GPIO_ENABLED */
- 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */
- 0x08 /* MFP5 AIC32X4_MFP5_GPIO_INPUT */
