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	"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
20Optional 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
