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

	"ti,tas2505" TAS2505, TAS2521

 - 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= <
