DeviceTree: AudioMux with no Code-Node

gdobato — Wed, 06 Apr 2016 19:44:07 GMT

Hello, I would like to know how I can implement on DT the Audio-Mux without specifying a Codec-Node.

On one hand, I have a sgtl500 connected to SSI1 as a Master which works fine. Below the structure in DT:

sound {

compatible = "fsl,imx6-wandboard-sgtl5000",

"fsl,imx-audio-sgtl5000";

model = "imx6-sgtl5000";

ssi-controller = <&ssi1>;

audio-codec = <&codec>;

audio-routing =

"MIC_IN", "Mic Jack",

"Mic Jack", "Mic Bias",

"Headphone Jack", "HP_OUT";

mux-int-port = <1>;

mux-ext-port = <3>;

};

&i2c3 {

clock-frequency = <100000>;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_i2c3>;

status = "okay";

codec: sgtl5000@0a {

compatible = "fsl,sgtl5000";

reg = <0x0a>;

clocks = <&clks 201>;

VDDA-supply = <&reg_3p3v>;

VDDIO-supply = <&reg_3p3v>;

VDDD-supply = <&reg_1p5v>;

};

On the other hand, I have a bluetooth connected to SSI2 via AUD5, so I need to specify the multiplexing between port-int-2 and port-ext-5, but as I said before, without specifying a audio codec.

How can I do it ? Is there a driver for that compatible with Device Tree ?

Thank you in advance.

Gabriel

Hi Gabriel

you are right: codec node is optional according to

Linux/Documentation/devicetree/bindings/sound/fsl,ssi.txt

linux-2.6-imx.git - Freescale i.MX Linux Tree

Best regards
