Analog Devices ADAU1977/ADAU1978/ADAU1979
Datasheets:

This driver supports both the I2C and SPI bus.
Required properties:
- compatible: Should contain one of the following:
"adi,adau1977"
"adi,adau1978"
"adi,adau1979"
- AVDD-supply: analog power supply for the device, please consult
Documentation/devicetree/bindings/regulator/regulator.txt
Optional properties:
- reset-gpios: the reset pin for the chip, for more details consult
Documentation/devicetree/bindings/gpio/gpio.txt
- DVDD-supply: supply voltage for the digital core, please consult
Documentation/devicetree/bindings/regulator/regulator.txt
- adi,micbias: configures the voltage setting for the MICBIAS pin.
Select 0/1/2/3/4/5/6/7/8 to specify MICBIAS voltage
5V/5.5V/6V/6.5V/7V/7.5V/8V/8.5V/9V
If not specified the default value will be "7" meaning 8.5 Volts.
This property is only valid for the ADAU1977
For required properties on SPI, please consult
Documentation/devicetree/bindings/spi/spi-bus.txt
Required properties on I2C:
- reg: The i2c address. Value depends on the state of ADDR0
and ADDR1, as wired in hardware.
Examples:
adau1977_spi: adau1977@0 {
compatible = "adi,adau1977";
spi-max-frequency = <600000>;
AVDD-supply = <&regulator>;
DVDD-supply = <&regulator_digital>;
adi,micbias = <3>;
reset-gpios = <&gpio 10 GPIO_ACTIVE_LOW>;
};
adau1977_i2c: adau1977@11 {
compatible = "adi,adau1977";
reg = <0x11>;
AVDD-supply = <&regulator>;
DVDD-supply = <&regulator_digital>;
reset-gpios = <&gpio 10 GPIO_ACTIVE_LOW>;
};
