   5 Required properties:
   6
   7 - compatible : "maxim,max98090" or "maxim,max98091".
   8
   9 - reg : The I2C address of the device.
  10
  11 - interrupts : The CODEC's interrupt output.
  12
  13 Optional properties:
  14
  15 - clocks: The phandle of the master clock to the CODEC
  16
  17 - clock-names: Should be "mclk"
  18
  19 - maxim,dmic-freq: Frequency at which to clock DMIC
