+This driver supports both the I2C and SPI bus.
+
+Required properties:
+ - compatible: Should contain one of the following:
+               "adi,adau1977"
+               "adi,adau1978"

+
+ - DVDD-supply: supply voltage for the digital core, please consult
+                Documentation/devicetree/bindings/regulator/regulator.txt
+
+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.
