Merge tag 'regulator-fix-v4.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fixes from Mark Brown:
"Some driver specific fixes for the regulator subsystem:
- Some of the changes to the core that were merged in the last merge
window exposed the fact that the qcom-smd driver hadn't implemented
the voltage enumeration interfaces like it should. Since it's a
simple driver specific fix to implement them do that.
- Fix the ramp delay configuration for tps51632"
