Merge tag 'gpio-updates-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We have lots of small changes all over the place, but no huge reworks
  or new drivers:

   - use ioread()/iowrite() interfaces instead of raw inb()/outb() in
     drivers

   - make irqchips immutable due to the new warning popping up when
     drivers try to modify the irqchip structures

   - add new compatibles to dt-bindings for realtek-otto, renesas-rcar
     and pca95xx

   - add support for new models to gpio-rcar, gpio-pca953x &
     gpio-realtek-otto

   - allow parsing of GPIO hogs represented as children nodes of
     gpio-uniphier

   - define a set of common GPIO consumer strings in dt-bindings

   - shrink code in gpio-ml-ioh by using more devres interfaces

   - pass arguments to devm_kcalloc() in correct order in gpio-sim

   - add new helpers for iterating over GPIO firmware nodes and
     descriptors to gpiolib core and use it in several drivers

   - drop unused syscon_regmap_lookup_by_compatible() function

   - correct format specifiers and signedness of variables in GPIO ACPI

   - drop unneeded error checks in gpio-ftgpio

   - stop using the deprecated of_gpio.h header in gpio-zevio

   - drop platform_data support in gpio-max732x

   - simplify Kconfig dependencies in gpio-vf610

   - use raw spinlocks where needed to make PREEMPT_RT happy

   - fix return values in board files using gpio-pcf857x

   - convert more drivers to using fwnode instead of of_node

   - minor fixes and improvements in gpiolib core"
