GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software nodes
- allow matching GPIO controllers by secondary firmware node if matching
by primary does not succeed
- demote deferral warnings to debug level as they are quite normal when
using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig by
default
- rework several core functions in preparation for the upcoming Revocable
helper library for protecting resources against sudden removal, this
reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by using
FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required
New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol to
control GPIOs (along with SCMI changes pulled from the pinctrl tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in several
GPIO drivers by normalizing any values other than 0, 1 or negative error
numbers
- use flexible arrays in several drivers to reduce the number of required
memory allocations
- simplify synchronous waiting for virtual drivers to probe and remove the
dedicated, a bit overengineered helper library dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers and
subsystems
- convert the two remaining users of of_get_named_gpio() to using GPIO
descriptors and remove the (no longer used) function along with the
header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from gpio-ts4800,
it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path on
OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse
Tests:
- add selftests for use-after-free cases in GPIO character device code
DT bindings:
- add a DT binding document for SCMI based, gpio-over-pinctrl devices
- fix interrupt description in microchip,mpfs-gpio
- add new compatible for gpio-realtek-otto
- describe the resets of the mpfs-gpio controller
- fix maintainer's email in gpio-delay bindings
- remove the binding document for cavium,thunder-8890 as the corresponding
device is bound over PCI and not firmware nodes
Documentation:
- update the recommended way of converting legacy boards to using software
nodes for GPIO description
- describe GPIO line value semantics
- misc updates to kerneldocs
Misc:
- convert OMAP1 ams-delta board to using GPIO hogs described with software
nodes

Merge tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.

exists but has not been registered as a firmware node yet
