Merge tag 'regmap-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie...

Pull regmap updates from Mark Brown:
 "Another small update for regmap, we have one new feature plus a little
  bit of cleanup:

   - Support for sparseness information in the flat cache, allowing
     users that really need the performance properties it provides to
     benefit from the interface and startup time improvements that
     sparsness provides without needing to go all the way to a more
     fancy data structure

   - Cleanup work from Andy Shevchenko, refactoring the cache interface
     in preparation for some future stuff he's working on"
