Introduce a new optional 'value_xlate' callback. This routine allows drivers
to translate or modify the register value and mask immediately before a write
operation. It is particularly useful for hardware that requires additional
control bits, such as a write-enable bit, to be appended to the data
dynamically.

Extend the reg_mask_xlate callback with an operation type parameter
(enum gpio_regmap_operation) to allow drivers to return different
register/mask combinations depending on the specific GPIO operation.
Consequently, update all existing drivers utilizing the gpio-regmap
framework (across drivers/gpio, drivers/iio, and drivers/pinctrl)
to accommodate the new reg_mask_xlate function signature.

When GPIO regmap based driver supplies its own IRQ domain, it might
still want to keep track of the IRQ requests and releases, in particular
to prevent a GPIO, which is used and locked as IRQ, to be requested
via standard ways. Provide default callbacks for such cases and keep
struct gpio_chip private to GPIO regmap implementation.

The direction of a single-ended (open-drain or open-source) GPIO line
cannot always be reliably determined by reading hardware registers.
In true open-drain implementations, the "high" state is achieved by
entering a high-impedance mode, which many hardware controllers report
as "input" even if the software intends to use it as an output.
This creates issues for consumer drivers (like I2C) that rely on
gpiod_get_direction() to decide if a line can be driven.
Introduce gpiod_is_single_ended() to allow consumers to check the
software configuration (GPIO_FLAG_OPEN_DRAIN/GPIO_FLAG_OPEN_SOURCE) of
a descriptor. This provides a robust way to identify lines that are
capable of being driven, regardless of their instantaneous hardware state.

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 GPIO controllers such as the one present in the LX2160ARDB
QIXIS FPGA which have fixed-direction input and output GPIO lines mixed
together in a single register. This cannot be modeled using the
gpio-regmap as-is since there is no way to present the true direction of
a GPIO line.
In order to make this use case possible, add a new configuration
parameter - fixed_direction_output - into the gpio_regmap_config
structure. This will enable user drivers to provide a bitmap that
represents the fixed direction of the GPIO lines.

With all users of bgpio_init() converted to using the modernized generic
GPIO chip API, we can now move the gpio-mmio-specific fields out of
struct gpio_chip and into the dedicated struct gpio_generic_chip. To
that end: adjust the gpio-mmio driver to the new layout, update the
docs, etc.
The changes in gpio-mlxbf2.c and gpio-mpc8xxx.c are here and not in their
respective conversion commits because the former passes the address of
the generic chip's lock to the __releases() annotation and we cannot
really hide it while gpio-mpc8xxx.c accesses the shadow registers in a
driver-specific workaround and there's no reason to make them available
in a public API.
Also: drop the relevant task from TODO as it's now done.

Add support to register for GPIO<->pin mapping using a list of non
consecutive pins. The core already supports sparse pin range (pins member
of struct pinctrl_gpio_range), but it was not possible to register one. If
pins is not NULL the core uses it, otherwise it assumes that a consecutive
pin range was registered and it uses pin_base.
The function gpiochip_add_pin_range() which allocates and fills the struct
pinctrl_gpio_range was renamed to gpiochip_add_pin_range_with_pins() and
the pins parameter was added.
Two new functions were added, gpiochip_add_pin_range() and
gpiochip_add_sparse_pin_range() to register a consecutive or sparse pins
range. Both use gpiochip_add_pin_range_with_pins().

As the first step in removing the fields specific to the gpio-mmio
module from struct gpio_chip, we introduce a new set of generic GPIO
chip interfaces that are meant to replace the existing bgpio_ ones.
The new initialization function - gpio_generic_chip_init() - takes a
configuration structure as argument instead of 9 separate parameters.
This will allow easy extension if needed in the future. We hide the
locking details behind a set of helpers in order to be able to move the
raw spinlock out of struct gpio_chip without the users noticing.
For now, the new APIs just wrap the existing ones. Once all users have
been converted to the new interfaces, we'll pull them into gpio-mmio and
implement them in a backward-compatible way while also moving all fields
specific to the generic GPIO chip into struct gpio_generic_chip.

The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where
applicable which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which
will take off the burden from GPIO drivers of checking this down
the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter
callbacks
- convert more drivers to making the irq_chip immutable as is
recommended by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built
with COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that
makes the setup easier for user-space than the existing
driver-level sysfs attributes and also adds more advanced
configuration features (such as referring to aggregated lines by
their original names or modifying their names as exposed by the
aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the
global GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x

(new drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
