- model : The user-visible name of this sound complex
- - ssi-controller : The phandle of the i.MX SSI controller
+ - ssi-controller : The phandle of the i.MX SSI (or SAI) controller
- audio-codec : The phandle of the SGTL5000 audio codec
Note: The AUDMUX port numbering should start at 1, which is consistent with
hardware manual.
+Optional properties:
+ - fsl,no-audmux : boolean
+ Required for i.MX6UL (and maybe other SoCs)
+ which don't have an AUDMUX, but still
+ feature the same audio subsystem otherwise.
+
+Note: Setting this property will make mux-int-port and mux-ext-port
+obsolete.
+
+
Example:
sound {
mux-int-port = <1>;
mux-ext-port = <3>;
};
+
+or (e.g. for i.MX6UL):
+sound {
+ compatible = "karo,imx6ul-tx6ul-sgtl5000",
+ "fsl,imx-audio-sgtl5000";
+ model = "imx6ul-tx6ul-sgtl5000";
+ ssi-controller = <&sai2>;
+ audio-codec = <&sgtl5000>;
+ audio-routing =
+ "MIC_IN", "Mic Jack",
+ "Mic Jack", "Mic Bias",
+ "Headphone Jack", "HP_OUT";
+ fsl,no-audmux;
