Everest ES8328 audio CODEC
This device supports both I2C and SPI.
Required properties:
- compatible : "everest,es8328"
- DVDD-supply : Regulator providing digital core supply voltage 1.8 - 3.6V
- AVDD-supply : Regulator providing analog supply voltage 3.3V
- PVDD-supply : Regulator providing digital IO supply voltage 1.8 - 3.6V
- IPVDD-supply : Regulator providing analog output voltage 3.3V
- clocks : A 22.5792 or 11.2896 MHz clock
- reg : the I2C address of the device for I2C, the chip select number for SPI
Pins on the device (for linking into audio routes):
* LOUT1
* LOUT2
* ROUT1
* ROUT2
* LINPUT1
* RINPUT1
* LINPUT2
* RINPUT2
* Mic Bias
Example:
codec: es8328@11 {
compatible = "everest,es8328";
DVDD-supply = <&reg_3p3v>;
AVDD-supply = <&reg_3p3v>;
PVDD-supply = <&reg_3p3v>;
HPVDD-supply = <&reg_3p3v>;
clocks = <&clks 169>;
reg = <0x11>;
