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
