+Analog Devices ADAU1701
+
+Required properties:
+
+ - compatible:          Should contain "adi,adau1701"
+ - reg:                 The i2c address. Value depends on the state of ADDR0
+                        and ADDR1, as wired in hardware.
+
+Optional properties:
+
+ - reset-gpio:          A GPIO spec to define which pin is connected to the
+                        chip's !RESET pin. If specified, the driver will
+                        assert a hardware reset at probe time.
+ - adi,pll-mode-gpios:  An array of two GPIO specs to describe the GPIOs
+                        the ADAU's PLL config pins are connected to.
+                        The state of the pins are set according to the
+                        configured clock divider on ASoC side before the
+                        firmware is loaded.
+ - adi,pin-config:      An array of 12 numerical values selecting one of the
+                        pin configurations as described in the datasheet,
+                        table 53. Note that the value of this property has
+                        to be prefixed with '/bits/ 8'.
+
+Examples:
+
+        i2c_bus {
+                adau1701@34 {
+                        compatible = "adi,adau1701";
+                        reg = <0x34>;
+                        reset-gpio = <&gpio 23 0>;
+                        adi,pll-mode-gpios = <&gpio 24 0 &gpio 25 0>;
+                        adi,pin-config = /bits/ 8 <0x4 0x7 0x5 0x5 0x4 0x4
+                                                   0x4 0x4 0x4 0x4 0x4 0x4>;
+                };
+        };
