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>;
|
