The suffix "machine" means alsa machine driver for mt7986-wm8960. It might be better to use "machine" here. Or you prefer "sound" than "machine"? Best regards, Maso

I waited for some suggestion in mail below, but it seems Rob was a little busy. https://lore.kernel.org/lkml/8c6316e79e40406e4d46709f602dcb14a4c00562.camel@mediatek.com/ After gentle ping last week and receiving your advice, I thought that means to send the v3 patch and might discuss dtbingding in v3 series. So sorry for misunderstanding it, I'll check the details with Rob in v3 series then refine it in v4. Best regards, Maso

The problem is that you did not reference in this patch any ongoing discussion and further questions, so comment looks like addressed, while it was not. Rob said: "in a common schema and reference them " You said: "common part yaml and reference to it" so I think you both agreed on the same. The advice would be to create common binding which is then referenced by other and your bindings. However if you start doing it, you will notice that it is impossible, because you have conflicting types for "audio-codec", so you cannot have one definition. This leads to the point - property is probably wrong and you need dai-link with sound-dai property, just like most cards are doing. Best regards, Krzysztof

I'll reference to sound-card-common.yaml for audio-routing.
