Hi Jean
Thank you for clearing your problem. Sorry for my confusable email. But can I ask something ?
My concern is if audio side need to care/support "formal" graph style, I think all cpu/codec/card driver (and soc-core too ?) need to be updated, but it is too much for me. if fake graph style (like this patch) is OK, I'm happy to hack it more.
This "fake graph style" means it is supporting both graph's "remote-endpoint" and current simple-card's "sound-dai" (= not 100% graph style).
(snip)
So, in brief:
- the simple-card with only "sound-dai" works fine with or without a graph of ports,
- for a full use of the graph of ports, forget about the simple-card.
Q1 If we use full graph style card, and if it would like to reuse current existing CPU/CODEC driver, then, I think CPU/CODEC driver should support graph style too. (Now, I'm checking v4l2 side existing graph style driver) I know it is based on its current implementation, but basically YES ?
Q2 If Q1 was Yes, to keeping ABI compatibility, that CPU/CODEC driver should support both "phandle" and "graph" style ?
