Commit d5168406 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'regmap-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "This release we've seen a couple of updates to make some DT based APIs
  use fwnode instead, allowing their use with ACPI systems, and a few
  cleanups"

* tag 'regmap-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  regmap: fix duplicated word in <linux/regmap.h>
  regmap: Switch to use fwnode instead of OF one
  regmap-irq: use fwnode instead of device node in add_irq_chip()
  regmap: remove stray space
  regmap: convert all regmap_update_bits() and co. macros to static inlines
