Merge tag 'regmap-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap fixes from Mark Brown:
 "Several bug fixes for issues that have been lurking for a while:

   - Check that devices haven't set the flag saying they only support
     register at a time operation while we're doing cache syncs,
     otherwise we fail to restore caches

   - Ensure that we don't mark all registers on devices using
     format_write() as cacheable, avoiding adding a cache of things like
     reset registers which we don't want to rewrite during cache sync

   - Make sure we create the debugfs files in the correct directory"

* tag 'regmap-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  regmap: Don't attempt block writes when syncing cache on single_rw devices
  regmap: Fix handling of volatile registers for format_write() chips
  regmap: Fix regcache debugfs initialization
