No, it clearly doesn't...
Right, it supports AC97.
The problem with doing this is that since AC'97 is an enumerable bus we really shouldn't need to list AC'97 CODECs in the device tree.
Ok, I understand that.
Instead we should be probing at runtime (as the non-ASoC AC'97 code does) or something similar.
When you say "non-ASoC AC'97 code", which file are you referring to ? Is it sound/pci/ac97/ac97_codec.c ?
If so is there already a table of tuples (AC97_VENDOR_ID1, AC97_VENDOR_ID2) -> (platform device, platform device data) and a matching mechanism already available to the ASoC drivers ?
Cheers.
