As I have said a number of times with the exception of the AC97 the core
is basically there. Certainly as far as loading modules goes the work
that needs doing is all at the driver level. It'd be helpful if you'd
take this on board more - as things stand ASoC isn't doing any device
loading itself and relies on notifications from the individual drivers
that they're ready to use.
There's more stuff that needs doing in the core but I'm not going to
stop and wait for the drivers to catch up except in so much as it stops
other work - I only have the ability to test some devices and plenty of
stuff to be getting on with. The feature is there if people want to use
it and I'm insisting on it for new CODEC drivers.

As I have repeatedly explained to you there are particular issues with
AC97 which affect these drivers.

This is going down to the individual drivers for your systems using old
device instantiation methods. Someone needs to update the drivers.
