Merge tag 'gpio-updates-for-v5.13-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:

 - new driver for the Realtek Otto GPIO controller

 - ACPI support for gpio-mpc8xxx

 - edge event support for gpio-sch (+ Kconfig fixes)

 - Kconfig improvements in gpio-ich

 - fixes to older issues in gpio-mockup

 - ACPI quirk for ignoring EC wakeups on Dell Venue 10 Pro 5055

 - improve the GPIO aggregator code by using more generic interfaces
   instead of reimplementing them in the driver

 - convert the DT bindings for gpio-74x164 to yaml

 - documentation improvements

 - a slew of other minor fixes and improvements to GPIO drivers
