I'm now thinking that new one can detect normal-link, DPCM-link,
multi-CPU / multi-Codec, Codec-to-Codec as normal audio-graph feature.
And has .hook callback for Eeach board specific feature.
see my previous mail which was To:Pierre-Louis
But, it is still under idea, not yet fixed.

Yes, that is the reason why I'm discussing how to implement new driver.
If we have "-cc-" and you use it on upsteam,
we will keep current card driver as-is, and I will create new "card2" driver.
Because keeping compatible will be difficult.
But I'm not sure what should I do.

Thank you for your help !!

Best regards
