-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>;
