   3 Required properties:
   4
   5   - compatible          : "fsl,imx-audio-wm8962"
   6
   7   - model               : The user-visible name of this sound complex
   8
   9   - ssi-controller      : The phandle of the i.MX SSI controller
  10
  11   - audio-codec         : The phandle of the WM8962 audio codec
  12
  13   - audio-routing       : A list of the connections between audio components.
  14                           Each entry is a pair of strings, the first being the
  15                           connection's sink, the second being the connection's

  17                           pins, and the jacks on the board:
  18
  19                           Power supplies:
  20                            * Mic Bias
  21
  22                           Board connectors:
  23                            * Mic Jack
  24                            * Headphone Jack
  25                            * Ext Spk
  26
  27   - mux-int-port        : The internal port of the i.MX audio muxer (AUDMUX)
  28
  29   - mux-ext-port        : The external port of the i.MX audio muxer
  30
  31 Note: The AUDMUX port numbering should start at 1, which is consistent with
