  3. Required properties:
    4. 

  4. - compatible       : "fsl,imx-audio-es8328"
    5. 

  5. - model            : The user-visible name of this sound complex
    6. 

  6. - ssi-controller   : The phandle of the i.MX SSI controller
    7. 

  7. - jack-gpio        : Optional GPIO for headphone jack
    8. 

  8. - audio-amp-supply : Power regulator for speaker amps
    9. 

  9. - audio-codec      : The phandle of the ES8328 audio codec
    10. 

  10. - audio-routing    : A list of the connections between audio components.
    11. 

  11.                      Each entry is a pair of strings, the first being the
    12. 

  12. 		     connection's sink, the second being the connection's
    13. 

  13. 		     source. Valid names could be power supplies, ES8328
    14. 

  14. 		     pins, and the jacks on the board:
