   3 Required properties:
   4
   5  - compatible:          Should contain "adi,adau1701"
   6  - reg:                 The i2c address. Value depends on the state of ADDR0
   7                         and ADDR1, as wired in hardware.

   9 Optional properties:
  10
  11  - reset-gpio:          A GPIO spec to define which pin is connected to the
  12                         chip's !RESET pin. If specified, the driver will
  13                         assert a hardware reset at probe time.
  14  - adi,pll-mode-gpios:  An array of two GPIO specs to describe the GPIOs
  15                         the ADAU's PLL config pins are connected to.
  16                         The state of the pins are set according to the
  17                         configured clock divider on ASoC side before the
  18                         firmware is loaded.
  19  - adi,pin-config:      An array of 12 numerical values selecting one of the
  20                         pin configurations as described in the datasheet,
  21                         table 53. Note that the value of this property has
  22                         to be prefixed with '/bits/ 8'.
