I'm sorry, but I'm busy now. and I'm happy if someone try to support simple-card DT.

In my understanding, latest plan (agreement with ALSA ML ?) of simple-card DT support are...

   1) current snd_soc_register_codec() will replaced to use snd_soc_register_component().
   2) snd_soc_register_component() will have name <-> id exchange function for DT suport.
   3) simple-card supports DT by using above name <-> id exchange

Most biggest and difficult is 1) I think.
It needs more discussion how to do 1) ?

But someone (I forgot who is) is already trying to implement it ?
I'm not sure...

Best regards
