Merge tag 'regmap-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "Another busy release for regmap with the second half of the maple tree
  register cache implementation, there's some smaller optimisations that
  could be done but this should now be able to replace the rbtree cache
  for most devices.

  We also had a followup from Aidan MacDonald's refactoring of some of
  the regmap-irq interfaces, the conversion is complete so the old
  interfaces are removed. This means that even with the new features for
  the maple tree cache we'd have a nice negative diffstat were it not
  for the addition of a bunch more KUnit coverage.

  There's one GPIO patch in here, it was a dependency for a cleanup of
  an API in the regmap-irq code for which the gpio-104-dio-48e driver
  was the only user.

  Highlights:

   - The maple tree cache can now load in default values more
     efficiently, and is capabale of syncing multiple registers
     in a single write during cache sync

   - More KUnit coverage, including some coverage for raw I/O
     and a dummy RAM backed cache to support it

   - Removal of several old interfaces in regmap-irq now all
     users have been modernised"
