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"

* tag 'regulator-fix-v4.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: qcom_smd: add list_voltage callback
  regulator: qcom_smd: add regulator ops for pm8941 lnldo
