Merge tag 'topic/twl' into regulator-next

TWL specific changes, cross-merged with OMAP due to arch/arm wanting to
use the new ability to override the voltage set and get operations to
support the in-CPU voltage management.  The other changes are minor
fixes, the addition of a few new regulators and device tree support.
