   5 Required properties:
   6
   7 - compatible : "realtek,rt5660".
   8
   9 - reg : The I2C address of the device.
  10
  11 Optional properties:
  12
  13 - clocks: The phandle of the master clock to the CODEC
  14 - clock-names: Should be "mclk"
  15
  16 - realtek,in1-differential
  17 - realtek,in3-differential
  18   Boolean. Indicate MIC1/3 input are differential, rather than single-ended.
  19
  20 - realtek,poweroff-in-suspend
  21   Boolean. If the codec will be powered off in suspend, the resume should be
  22   added delay time for waiting codec power ready.
