1Texas Instruments - tlv320aic32x4 Codec module 2 3The tlv320aic32x4 serial control bus communicates through I2C protocols 4 5Required properties: 6 - compatible - "string" - One of: 7 "ti,tlv320aic32x4" TLV320AIC3204 8 "ti,tlv320aic32x6" TLV320AIC3206, TLV320AIC3256 9 - reg: I2C slave address 10 - supply-*: Required supply regulators are: 11 "iov" - digital IO power supply 12 "ldoin" - LDO power supply 13 "dv" - Digital core power supply 14 "av" - Analog core power supply 15 If you supply ldoin, dv and av are optional. Otherwise they are required 16 See regulator/regulator.txt for more information about the detailed binding 17 format. 18 19Optional properties: 20 - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt 21 - clocks/clock-names: Clock named 'mclk' for the master clock of the codec. 22 See clock/clock-bindings.txt for information about the detailed format. 23 - aic32x4-gpio-func - <array of 5 int> 24 - Types are defined in include/sound/tlv320aic32x4.h 25 26 27Example: 28 29codec: tlv320aic32x4@18 { 30 compatible = "ti,tlv320aic32x4"; 31 reg = <0x18>; 32 clocks = <&clks 201>; 33 clock-names = "mclk"; 34 aic32x4-gpio-func= < 35 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */ 36 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */ 37 0x04 /* MFP3 AIC32X4_MFP3_GPIO_ENABLED */ 38 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */ 39 0x08 /* MFP5 AIC32X4_MFP5_GPIO_INPUT */ 40 >; 41}; 42
