I am not sure it makes sense to stuff the rt5660 support in a machine
driver that's meant mostly for Chromebooks, and I am not sure why you
picked this one specifically.
Since there is no reuse of the DA7219, DMIC or MAX98357a, I would argue
that you want to define a new machine driver so that you only select and
compile in what you need, not to mention that it'll be easier to
maintain, both for upstream and for Chrome backports.
Thanks!
