+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'.
+ - avdd-supply: Power supply for AVDD, providing 3.3V
+ - dvdd-supply: Power supply for DVDD, providing 3.3V
+
+Examples:
+
+ i2c_bus {
+ adau1701@34 {
+ compatible = "adi,adau1701";
+ reg = <0x34>;
+ reset-gpio = <&gpio 23 0>;
+ avdd-supply = <&vdd_3v3_reg>;
+ dvdd-supply = <&vdd_3v3_reg>;
+ 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>;
+ };
