GPIO core:
- add sanitization of return values of GPIO provider callbacks so that invalid
ones don't get propagated to user-space
- add new variants of the line setter callbacks for GPIO providers that return
an integer and allow to indicate driver errors to the GPIO core
- change the interface of all gpiod_set_value() variants to return an integer
thus becoming able to indicate failures in the underlying layer to callers
- drop unneeded ERR_CAST in gpiolib-acpi
- use for_each_if() where applicable
- provide gpiod_multi_set_value_cansleep() as a new, simpler interface to
gpiod_set_array_value_cansleep() and use it across several drivers treewide
- reduce the number of atomic reads of the descriptor flags in gpiolib debugfs
code
- simplify for_each_hwgpio_in_range() and for_each_requested_gpio_in_range()
- add support for three-cell GPIO specifiers in GPIO OF code
- don't build HTE (hardware timestamp engine) GPIO code with the HTE subsystem
disabled in Kconfig
- unduplicate calls to gpiod_direction_input_nonotify()
- rework the handling of the valid_mask property of GPIO chips: don't allow
drivers to set it as it should only be handled by GPIO core and start
actually enforcing it in GPIO core for *all* drivers, not only the ones
implementing a custom request() callback
- get the `ngpios` property from the fwnode of the GPIO chip, not its device in
order to handle multi-bank GPIO chips
Driver improvements:
- convert a part of the GPIO drivers under drivers/gpio/ to using the new value
setter callbacks
- convert several drivers to using automatic lock guards from cleanup.h
- allow building gpio-bt8xx with COMPILE_TEST=y
- refactor gpio-74x164 (use devres, cleanup helpers, __counted_by() and bits.h
macros)
- refactor gpio-latch (use generic device properties, lock guards and some
local variables for better readability)
- refactor gpio-xilinx (improve the usage of the bitmap API)
- support multiple virtual GPIO controller instances in gpio-virtio
- allow gpio-regmap to use the standard `ngpios` property from GPIOLIB
- factor out the common code for synchronous probing of virtual GPIO devices
into its own library
- use str_enable_disable(), str_high_low() and other string helpers where
applicable
- extend the gpio-mmio abstraction layer to allow calling into the pinctrl
back-end when setting direction
- convert gpio-vf610 to using the gpio-mmio library
- use more devres in gpio-adnp
- add support for reset-gpios in gpio-pcf857x
- add support for more models to gpio-loongson-64bit
DT bindings:
- add new compatibles to gpio-vf610 and gpio-loongson
- add missing gpio-ranges property to gpio-mvebu
- add reset-gpios to nxp,pcf8575
- enable gpio-hog parsing in ast2400-gpio
Misc:
- coding style improvements
- kerneldoc fixes
- includes reordering
- updates to the TODO list

Pull gpio updates from Bartosz Golaszewski:
"There are no new drivers this time but several changes to the core
GPIO framework and various driver updates.
This release cycle, we're starting a relatively straightforward but
tedious rework of the GPIO consumer API: for historical reasons, the
gpiod_set_value() variants would return void. Not only that but the
GPIO provider interface does not even allow drivers to return a value
to GPIO core. This is because initial GPIO controllers would be MMIO
based and could not fail. We've had I2C, SPI and USB controllers for
years too but no way of indicating failures to callers.
This changes the consumer interface, adds new provider callbacks and
starts converting the drivers under drivers/gpio/ to using them. Once
this gets upstream, we'll keep on converting GPIO drivers that live
elsewhere and once there are no more users of the old callbacks, we'll
remove them and rename the new ones to the previous name. I imagine
the last step would happen in one sweeping change like what you did
for the remove_new() -> remove() renaming.
We've also addressed an issue where invalid return values from GPIO
drivers would get propagated to user-space by adding some
GPIO-core-level sanitization. Again: not a complex change but way
overdue.
Other than that: lots of driver and core refactoring, DT-bindings
changes and some other minor changes like coding style fixes or header
reordering.
