Merge tag 'regulator-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is an extremely quiet release for the regulator API, we've got a
  small set of bug fixes and minor feature enhancements for drivers plus
  a couple of more visible changes:

   - add support for ramp times in regulators that don't use selectors.

   - new driver for LTC3676"
