    1 Texas Instruments - tlv320aic32x4 Codec module
    2 
    3 The tlv320aic32x4 serial control bus communicates through I2C protocols
    4 
    5 Required properties:
    6  - compatible - "string" - One of:
    7         "ti,tlv320aic32x4" TLV320AIC3204
    8         "ti,tlv320aic32x6" TLV320AIC3206, TLV320AIC3256
    9         "ti,tas2505" TAS2505, TAS2521
   10  - reg: I2C slave address
   11  - supply-*: Required supply regulators are:
   12     "iov" - digital IO power supply
   13     "ldoin" - LDO power supply
   14     "dv" - Digital core power supply
   15     "av" - Analog core power supply
   16     If you supply ldoin, dv and av are optional. Otherwise they are required
   17    See regulator/regulator.txt for more information about the detailed binding
   18    format.
   19 
   20 Optional properties:
   21  - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
   22  - clocks/clock-names: Clock named 'mclk' for the master clock of the codec.
   23    See clock/clock-bindings.txt for information about the detailed format.
   24  - aic32x4-gpio-func - <array of 5 int>
   25         - Types are defined in include/sound/tlv320aic32x4.h
