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 - - 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 */ >; };
