Hi Rob
Why do we need these changes? I'm not wild about a new generic binding replacing an existing one which only has 2 or 3 users IIRC. Plus there's already the Renesas variant. (On the flip side, only a few users, easier to deprecate the old binding.)
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 !!
