Freescale i.MX audio complex with WM8962 codec
Required properties:
- compatible : "fsl,imx-audio-wm8962"
- 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 WM8962 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, WM8962 pins, and the jacks on the board:
Power supplies:
* Mic Bias
Board connectors:
* Mic Jack
* Headphone 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,imx6q-sabresd-wm8962",
"fsl,imx-audio-wm8962";
model = "wm8962-audio";
ssi-controller = <&ssi2>;
audio-codec = <&codec>;
audio-routing =
"Headphone Jack", "HPOUTL",
"Headphone Jack", "HPOUTR",
"Ext Spk", "SPKOUTL",
"Ext Spk", "SPKOUTR",
"MICBIAS", "AMIC",
"IN3R", "MICBIAS",
"DMIC", "MICBIAS",
"DMICDAT", "DMIC";
mux-int-port = <2>;
mux-ext-port = <3>;
};
