Freescale i.MX audio complex with ES8328 codec
Required properties:
- compatible : "fsl,imx-audio-es8328"
- model : The user-visible name of this sound complex
- ssi-controller : The phandle of the i.MX SSI controller
- jack-gpio : Optional GPIO for headphone jack
- audio-amp-supply : Power regulator for speaker amps
- audio-codec : The phandle of the ES8328 audio codec
- audio-routing : A list of the connections between audio components.
Each entry is a pair of strings, the first being the
connection's sink, the second being the connection's
source. Valid names could be power supplies, ES8328
pins, and the jacks on the board:
Power supplies:

* ROUT1
* ROUT2
* LINPUT1
* LINPUT2
* RINPUT1
* RINPUT2

Board connectors:
* Headphone
* Speaker
* Mic Jack
- mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
- mux-ext-port : The external port of the i.MX audio muxer (AUDMIX)
Note: The AUDMUX port numbering should start at 1, which is consistent with
hardware manual.
Example:
