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>;
    };
