   1Analog Devices ADAU1701
   2
   3Required 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.

   9Optional 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'.
