1*7e7292dbSSean CrossFreescale i.MX audio complex with ES8328 codec
2*7e7292dbSSean Cross
3*7e7292dbSSean CrossRequired properties:
4*7e7292dbSSean Cross- compatible       : "fsl,imx-audio-es8328"
5*7e7292dbSSean Cross- model            : The user-visible name of this sound complex
6*7e7292dbSSean Cross- ssi-controller   : The phandle of the i.MX SSI controller
7*7e7292dbSSean Cross- jack-gpio        : Optional GPIO for headphone jack
8*7e7292dbSSean Cross- audio-amp-supply : Power regulator for speaker amps
9*7e7292dbSSean Cross- audio-codec      : The phandle of the ES8328 audio codec
10*7e7292dbSSean Cross- audio-routing    : A list of the connections between audio components.
11*7e7292dbSSean Cross                     Each entry is a pair of strings, the first being the
12*7e7292dbSSean Cross		     connection's sink, the second being the connection's
13*7e7292dbSSean Cross		     source. Valid names could be power supplies, ES8328
14*7e7292dbSSean Cross		     pins, and the jacks on the board:
