Freescale i.MX audio complex with mqs codec
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible : "fsl,imx-audio-mqs"
|
||||||
|
- model : The user-visible name of this sound complex
|
||||||
|
- cpu-dai : The phandle of the i.MX sai controller
|
||||||
|
- audio-codec : The phandle of the mqs audio codec
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
sound-mqs {
|
||||||
|
compatible = "fsl,imx6sx-sdb-mqs",
|
||||||
|
"fsl,imx-audio-mqs";
|
||||||
|
model = "mqs-audio";
|
||||||
|
cpu-dai = <&sai1>;
|
||||||
|
audio-codec = <&mqs>;
