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.

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"

"There are two new drivers and some changes to GPIO core but mostly
just GPIO driver updates across a wide array of files, adding support
for new models as well as various refactoring changes. Nothing
controversial and everything has spent a good measure of time in
linux-next.

GPIOLIB core:
- shrink the GPIO bus driver stub code
- rework software node support for "undefined" software nodes
- provide and use devm_fwnode_gpiod_get_optional()
- only compile the OF quirk for MT2701 when needed

New drivers:
- add the GPIO driver for ROHM bd72720
- add the gpio-line-mux driver providing 1-to-many mapping for a
single real GPIO

Driver changes:
- refactor gpio-pca9570: use lock guard, add missing headers, use
devres consistently
- add support for a new model (G7 Aspeed sgpiom) to the aspeed-sgpio
driver along with some prerequisite refactoring
- use device_get_match_data() where applicable and save some lines
- add support for more models to gpio-cadence
- add the compatible property to reset-gpio and use it in shared GPIO
management
- drop unnecessary use of irqd_get_trigger_type() in gpio-max77759
- add support for a new variant to gpio-pca953x
- extend build coverage with COMPILE_TEST for more drivers
- constify configfs structures in gpio-sim and gpio-virtuser
- add support for the K3 SoC to gpio-spacemit
- implement the missing .get_direction() callback in gpio-max77620
- add support for Tegra264 to gpio-tegra186
- drop unneeded MODULE_ALIAS() from gpio-menz127

DT bindings:
- document support for the opencores GPIO controller in gpio-mmio
- document new variants for gpio-pca953x

gpio: Support ROHM BD72720 gpios

The ROHM BD72720 has 6 pins which may be configured as GPIOs. The
GPIO1 ... GPIO5 and EPDEN pins. The configuration is done to OTP at the
manufacturing, and it can't be read at runtime. The device-tree is
required to tell the software which of the pins are used as GPIOs.

Keep the pin mapping static regardless the OTP. This way the user-space
can always access the BASE+N for GPIO(N+1) (N = 0 to 4), and BASE + 5
for the EPDEN pin. Do this by setting always the number of GPIOs to 6,
and by using the valid-mask to invalidate the pins which aren't configured
as GPIOs.

First two pins can be set to be either input or output by OTP. Direction
can't be changed by software. Rest of the pins can be set as outputs
only. All of the pins support generating interrupts.

Support the Input/Output state getting/setting and the output mode
configuration (open-drain/push-pull).

gpio: add gpio-line-mux driver

Add a new driver which provides a 1-to-many mapping for a single real
GPIO using a multiplexer. Each virtual GPIO corresponds to a multiplexer
state which, if set for the multiplexer, connects the real GPIO to the
corresponding virtual GPIO.

This can help in various usecases. One practical case is the special
hardware design of the Realtek-based XS1930-10 switch from Zyxel. It
features two SFP+ ports/cages whose signals are wired directly to the
switch SoC. Although Realtek SoCs are short on GPIOs, there are usually
enough the fit the SFP signals without any hacks.

However, Zyxel did some weird design and connected RX_LOS, MOD_ABS and
TX_FAULT of one SFP cage onto a single GPIO line controlled by a
multiplexer (the same for the other SFP cage). The single multiplexer
controls the lines for both SFP and depending on the state, the
designated 'signal GPIO lines' are connected to one of the three SFP
signals.

Because the SFP core/driver doesn't support multiplexer but needs single
GPIOs for each of the signals, this driver fills the gap between both.
It registers a gpio_chip, provides multiple virtual GPIOs and sets the
backing multiplexer accordingly.

Due to several practical issues, this is input-only and doesn't support
IRQs.
