ASoC folks, Mark, Liam, I would really appreciate your take on the idea if you could spare a few moments please. Actually I just might get our AP design folks to implement such a dedicated shifter IP in later SoC. Also, I don't wanna direct the bloke(Angat) in a direction that is outright unacceptable to maintainers -- if it is so.
