Merge tag 'regulator-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"A couple of nice new features this month, the ability to map
regulators in order to allow voltage control by external coprocessors
is something people have been asking for for a long time.
- improved support for switch only "regulators", allowing current
state to be read from the parent regulator but no setting.
- support for obtaining the register access method used to set
voltages, for use in systems which can offload control of this to a
coprocessor (typically for DVFS).
- support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
TPS65917"
