Sorry I don't understand - Who is "2 or 3 users" ? - What is "Renesas variant" ? audio-graph-card2 is based on audio-graph-card, but different driver not minor variant. Becase these are different, it can't keep compatibility. This is the reason why we need audio-graph-card2 instead of expanding audio-graph-card. > I also would like to see the graph card replace the simple card > binding. Surely it can handle the 'simple' case too. Do you mean you want to merge audio-graph-card and simple-card DT binding ?? audio-graph-card and simple-card are different drivers. Thank you for your help !!
