Merge tag 'regmap-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "A quiet release for regmap: we've seen several cleanups, an update for
  a change in the MDIO APIs and one small fix"

* tag 'regmap-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  regmap-irq: Remove unused mask_invert flag
  regmap-irq: Remove unused type_invert flag
  regmap: Reorder fields in 'struct regmap_bus' to save some memory
  regmap: apply reg_base and reg_downshift for single register ops
