Merge tag 'gpio-updates-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "The gpio-sim module is back, this time without any changes to
  configfs. This results in a less elegant user-space interface but I
  never got any follow-up on the committable items and didn't want to
  delay this module for several more months.

  Other than that we have support for several new models and some
  support going away. We started working on converting GPIO drivers to
  using fwnode exclusively in order to limit references to OF symbols to
  gpiolib-of.c exclusively. We also have regular tweaks and improvements
  all over the place.

  Summary:

   - new testing module: gpio-sim that is scheduled to replace
     gpio-mockup

   - initial changes aiming at converting all GPIO drivers to using the
     fwnode interface and limiting any references to OF symbols to
     gpiolib-of.c

   - add support for Tegra234 and Tegra241 to gpio-tegra186

   - add support for new models (SSD201 and SSD202D) to gpio-msc313

   - add basic support for interrupts to gpio-aggregator

   - add support for AMDIF031 HID device to gpio-amdpt

   - drop support for unused platforms in gpio-xlp

   - cleanup leftovers from the removal of the legacy Samsung Exynos
     GPIO driver

   - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make
     PREEMPT_RT happy

   - generalize the common 'ngpios' device property by reading it in the
     core gpiolib code so that we can remove duplicate reads from
     drivers

   - allow line names from device properties to override names set by
     drivers

   - code shrink in gpiod_add_lookup_table()

   - add new model to the DT bindings for gpio-vf610

   - convert DT bindings for tegra devices to YAML

   - improvements to interrupt handling in gpio-rcar and gpio-rockchip

   - updates to intel drivers from Andy (details in the merge commit)

   - some minor tweaks, improvements and coding-style fixes all around
     the subsystem"
