| 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 */ |
