-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:
- * audio-amp
-
- ES8328 pins:
- * LOUT1
- * LOUT2
- * ROUT1
- * ROUT2
- * LINPUT1
- * LINPUT2
- * RINPUT1
- * RINPUT2
- * Mic PGA
-
- 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:
-
