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.
|
|
|
|

|
|
|
|
sound {
|
|
compatible = "fsl,imx6q-sabresd-wm8962",

"fsl,imx-audio-wm8962";
|
|
model = "wm8962-audio";
|
|
ssi-controller = <&ssi2>;
|
|
audio-codec = <&codec>;
|
