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
