Hi Linus!
This is the main pull-request from the GPIO subsystem for the next release
cycle.
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.
The details are in the signed tag. Please pull!
Best Regards,
Bartosz Golaszewski

gpio: rcar: Propagate errors from devm_request_irq() (2022-01-05 09:57:34 +0100)
----------------------------------------------------------------
gpio updates for v5.17
- 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
