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 - reg: I2C slave address
10 - supply-*: Required supply regulators are:
11 "iov" - digital IO power supply
12 "ldoin" - LDO power supply
13 "dv" - Digital core power supply
14 "av" - Analog core power supply
15 If you supply ldoin, dv and av are optional. Otherwise they are required
16 See regulator/regulator.txt for more information about the detailed binding
17 format.
18
19Optional properties:
20 - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
21 - clocks/clock-names: Clock named 'mclk' for the master clock of the codec.
22 See clock/clock-bindings.txt for information about the detailed format.
23 - aic32x4-gpio-func - <array of 5 int>
24 - Types are defined in include/sound/tlv320aic32x4.h
