Merge tag 'regmap-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "This has been a busy release for regmap.

  By far the biggest set of changes here are those from Markus Pargmann
  which implement support for block transfers in smbus devices.  This
  required quite a bit of refactoring but leaves us better able to
  handle odd restrictions that controllers may have and with better
  performance on smbus.

  Other new features include:

   - Fix interactions with lockdep for nested regmaps (eg, when a device
     using regmap is connected to a bus where the bus controller has a
     separate regmap).  Lockdep's default class identification is too
     crude to work without help.

   - Support for must write bitfield operations, useful for operations
     which require writing a bit to trigger them from Kuniori Morimoto.

   - Support for delaying during register patch application from Nariman
     Poushin.

   - Support for overriding cache state via the debugfs implementation
     from Richard Fitzgerald"
