Merge tag 'regulator-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"A fairly quiet release again, a couple of relatively small new
features and a bunch of driver specific work including yet more code
elimination and fixes from Axel Lin.
- Addidion of linear_min_sel for offsetting linear selectors in the
helpers.
- Support for continuous voltage ranges for regulators with extremely
high resolution.
- Drivers for AS3711, DA9055, MAX9873, TPS51632, TPS80031 and ARM
vexpress."
Fix up trivial conflict (due to typo fix) in palmas-regulator.c
