I'm a strong advocate of consistency in naming and using twl4030 prefixes for
drivers that are common to more twl chips looks very inconsistent to me.
Besides, some common twl drivers are already using the twl prefix, so this can
also be seen as harmonisation.
> Regarding this patch - pls, do not mix Kconfig and code changes.
Do you mean that for code changes that are directly affected by Kconfig changes
(e.g. #ifdef CONFIG_)? Is the policy that "each commit must produce a working
result" or is it okay to break drivers in between commits of the same series?

Noted, I'll come up with something for v2.
