+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= <
+ 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */

+ 0x04 /* MFP3 AIC32X4_MFP3_GPIO_ENABLED */
+ 0xff /* AIC32X4_MFPX_DEFAULT_VALUE */
+ 0x08 /* MFP5 AIC32X4_MFP5_GPIO_INPUT */
