Hi Nikita
Example usage:
codec: tlv320dac3100@18 { compatible = "ti,tlv320dac3100"; ... }
amp: tpa6130a2@60 { compatible = "ti,tpa6130a2"; ... }
sound { compatible = "simple-audio-card"; ... simple-audio-card,widgets = "Headphone", "Headphone Jack"; simple-audio-card,routing = "Headphone Jack", "HPLEFT", "Headphone Jack", "HPRIGHT", "LEFTIN", "HPL", "RIGHTIN", "HPR"; simple-audio-card,aux-devs = <&>; simple-audio-card,cpu { sound-dai = <&ssi2>; }; simple-audio-card,codec { sound-dai = <&codec1>; clocks = ... };
This case, I think you want ...
simple-audio-card,codec { - sound-dai = <&codec1>; + sound-dai = <&codec>;

I think it is very helpful if this document has above sample
