i.MX6 device tree of Linux Yocto BSP can set audmux connection?

[satoshishimoda]

Hi community,

I have a question about device tee of i.MX6 Linux BSP (L3.14.28_1.0.0-ga).

I think device tree includes each module setting.

Then, I want to know whether device tree can set audiomux connection also.

(e.g. SSI1 --> AUDMUX port1 --(Internal Network Mode)--> AUDMUX port 4 )

Best Regards,

I think you can take the dtsi file in the BSP for reference.

e.g. imx6qdl-sabresd.dtsi. mux-int-port and mux-ext-port is used to set the AUDMUX in/out port number.

under the :

     sound {    

                    compatible = "fsl,imx6q-sabresd-wm8962",

                    ...

                    ...

                    ...

                    mux-int-port = <2>;

                    mux-ext-port = <3>;

For more details, please read the linux documentation. Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt
