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>;
};
