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:
sound {
compatible = "fsl,imx-audio-es8328";
model = "imx-audio-es8328";
ssi-controller = <&ssi1>;
audio-codec = <&codec>;
jack-gpio = <&gpio5 15 0>;
audio-amp-supply = <®_audio_amp>;
audio-routing =
"Speaker", "LOUT2",
"Speaker", "ROUT2",
"Speaker", "audio-amp",
"Headphone", "ROUT1",
"Headphone", "LOUT1",
"LINPUT1", "Mic Jack",
"RINPUT1", "Mic Jack",
"Mic Jack", "Mic Bias";
mux-int-port = <1>;
mux-ext-port = <3>;
};
