For sure we need to have the card level DAPM map, when we have more than one codec in the system. What I was thinking is more like to move the DAPM map from codec domain up to card level. What I mean is, that when you build up your ASoC card, the DAPM map/routes are going to be attached to the card, and not to the codec.
Actually paths and widgets are already decoupled from codec and moved to card domain. Map/route is initialization time thing which still has dependency to codec. I.e. snd_soc_dapm_add_route favors a widget from a calling dapm context (codec).
This is due if there are machines with multiple codecs that are not cross-connected but if they have widgets with a same name and I didn't want to force them to use name prefixing and thus causing userspace-kernel space breakage (kcontrol names changed) compared to current implementation.
