Of course we could try, but I suggest that it should be done separately from this series. Certainly it will take a lot of extra effort and this series isn't about improving older drivers, it's about enabling h/w support for the RT5631 codec. It shouldn't be a problem to switch to the common machine driver later on if this driver will turn out to be feasible.
