Freescale i.MX audio complex with WM8960 codec
Required properties:
- compatible : "fsl,imx-audio-wm8960", "fsl,imx7d-evk-wm8960"
- model : The user-visible name of this sound complex
- cpu-dai : The phandle of CPU DAI
- audio-codec : The phandle of the WM8960 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, WM8960
pins, and the jacks on the board:
Power supplies:
* Mic Bias
Board connectors:
* Mic Jack
* Headphone Jack
* Ext Spk
Optional properties:
- hp-det-gpios : The gpio pin to detect plug in/out event that happens to
Headphone jack.
- mic-det-gpios: The gpio pin to detect plug in/out event that happens to
Microphone jack.
Example:
sound: sound {
compatible = "fsl,imx7d-evk-wm8960",
"fsl,imx-audio-wm8960";
model = "wm8960-audio";
cpu-dai = <&sai1>;
audio-codec = <&wm8960>;
codec-master;
/*
* hp-det = <hp-det-pin hp-det-polarity>;
* hp-det-pin: JD1 JD2 or JD3
* hp-det-polarity = 0: hp detect high for headphone
* hp-det-polarity = 1: hp detect high for speaker
*/
hp-det = <2 0>;
hp-det-gpios = <&gpio1 0 0>;
mic-det-gpios = <&gpio1 0 0>;
