Freescale i.MX audio complex with SGTL5000 codec
|
|
|
|
Required properties:
|
|
|
|
- compatible : "fsl,imx-audio-sgtl5000"
|
|
|
|
- model : The user-visible name of this sound complex
|
|
|
|
- ssi-controller : The phandle of the i.MX SSI controller
|
|
|
|
- audio-codec : The phandle of the SGTL5000 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, SGTL5000
|
|
pins, and the jacks on the board:
|
|
|
|
Power supplies:
|
|
* Mic Bias
|
|
|
|
SGTL5000 pins:
|
|
* MIC_IN
|
|
* LINE_IN
|
|
* HP_OUT
|
|
* LINE_OUT
|
|
|
|
Board connectors:
|
|
* Mic Jack
|
|
* Line In Jack
|
|
* Headphone Jack
|
|
* Line Out Jack
|
|
* Ext Spk
|
|
|
|
- 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
|
|
|
|
Note: The AUDMUX port numbering should start at 1, which is consistent with
|
|
hardware manual.
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "fsl,imx51-babbage-sgtl5000",
|
|
"fsl,imx-audio-sgtl5000";
|
|
model = "imx51-babbage-sgtl5000";
|
|
ssi-controller = <&ssi1>;
|
|
audio-codec = <&sgtl5000>;
|
|
audio-routing =
|
|
"MIC_IN", "Mic Jack",
|
|
"Mic Jack", "Mic Bias",
|
|
"Headphone Jack", "HP_OUT";
|
|
mux-int-port = <1>;
|
|
mux-ext-port = <3>;
|
|
};
