Prefs
   1Freescale i.MX audio complex with WM8962 codec
   2
   3Required properties:
   4- compatible : "fsl,imx-audio-wm8962"
   5- model : The user-visible name of this sound complex
   6- ssi-controller : The phandle of the i.MX SSI controller
   7- audio-codec : The phandle of the WM8962 audio codec
   8- audio-routing : A list of the connections between audio components.
   9  Each entry is a pair of strings, the first being the connection's sink,
  10  the second being the connection's source. Valid names could be power
  11  supplies, WM8962 pins, and the jacks on the board:
  12
  13  Power supplies:
  14   * Mic Bias
  15
  16  Board connectors:
  17   * Mic Jack
  18   * Headphone Jack
  19   * Ext Spk
  20
  21- mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
  22- mux-ext-port : The external port of the i.MX audio muxer
  23
  24Note: The AUDMUX port numbering should start at 1, which is consistent with
  25hardware manual.
