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
|
|

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.
