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
