Merge tag 'regmap-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"After several quiet kernel releases we've got a couple of new features
in regmap, support for using hwspinlocks as the lock for the internal
data structures and a helper for polling on regmap_fields. The Kconfig
dependencies on hwspinlocks were annoyingly difficult to squash
between things behaving surprisingly and randconfig, I could've
squashed those commits down but might've have caused hassle with other
trees trying to use the new support.
- support for using a hwspinlock to protect the regmap
- an iopoll style helper for regmap_field"
