As for the twl-regulator I still have plan to do a major cleanup there. It is
just sad that it received the DT bindings for the current code. The DT support
addition would have been the perfect place to sanitize it. Now it is just
going to be a huge pain in the back.

As for the 32k clock:
I don't know the state of the common clock framework for OMAPs. Is it already
up in 3.7? Or going for 3.8? 3.9? 3.10?...
We need CCF to resolve this. I can cook up the clock driver for the 32k clock
from twl, but in order to use it we need CCF on OMAP.
