Before going into detail review, I see real issue in the overall
approach here to add new interface to exiting lpass!!
Intention of struct lpass_variant is to address differences between SoCs
or different lpass versions. But you should not duplicate this and use
it for addressing differences between each lpass interfaces!
All the dai related register offsets should still go in to this
structure and driver should be able to know which dai its talking to
based on snd_soc_dai_driver id and select correct register offset.
Also on the other note, can you please split the patch if possible so
that it will be easy for review. Specially I would like to see header
file changes specific to adding new interface to be separate then
followed by the actual interface implementation and then the user.
I also see some unrelated changes like changing buffer sizes, which
should go into different patch!
