Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.
The single merge pulls in changes that remove all usage of global GPIO
numbers from arch/arm/mach-omap.

Add support for the BlueField-3 SoC GPIO driver.
This driver configures and handles GPIO interrupts. It also enables a user
to manipulate certain GPIO pins via libgpiod tools or other kernel drivers.
The usables pins are defined via the "gpio-reserved-ranges" property.

Add support for TPS65219 PMICs GPIO interface.
3 GPIO pins:
- GPIO0 only is IO but input mode reserved for MULTI_DEVICE_ENABLE usage.
- GPIO1 and GPIO2 are Output only and referred as GPO1 and GPO2 in spec.
GPIO0 is statically configured as input or output prior to Linux boot.
it is used for MULTI_DEVICE_ENABLE function.
This setting is statically configured by NVM.
GPIO0 can't be used as a generic GPIO (specification Table 8-34).
It's either a GPO when MULTI_DEVICE_EN=0 or a GPI when MULTI_DEVICE_EN=1.
Datasheet describes specific usage for non standard GPIO.

The main purpose is to address external, passive delays upon line
voltage changes.

In fact the device with chip id 0xD283 is called NCT6126D, and that is
the chip id the Nuvoton code was written for. Correct that name to avoid
confusion, because a NCT6116D in fact exists as well but has another
chip id, and is currently not supported.
The look at the spec also revealed that GPIO group7 in fact has 8 pins,
so correct the pin count in that group as well.

- Introduce Intel Tangier GPIO driver
Add minimal driver for Fairchild FXL6408 8-bit I2C-controlled GPIO expander
using the generic regmap based GPIO driver (GPIO_REGMAP).
The driver implements setting the GPIO direction, reading inputs
and writing outputs.
In addition to that the FXL6408 has the following functionalities:
- allows to monitor input ports for data transitions with an interrupt pin
- all inputs can be configured with pull-up or pull-down resistors

Now that coldfire is the only user of a custom asm/gpio.h, it seems
better to remove this as well, and have the same interface everywhere.
For the gpio_get_value()/gpio_set_value()/gpio_to_irq(), gpio_cansleep()
functions, the custom version is only a micro-optimization to inline the
function for constant GPIO numbers. However, in the coldfire defconfigs,
I was unable to find a single instance where this micro-optimization
was even used, and according to Geert the only user appears to be the
QSPI chip that is disabled everywhere.
The custom gpio_request_one() function is even less useful, as it is
guarded by an #ifdef that is never true.

REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the
subsystem trees, but they should all be trivial to resolve by removing
the files.

simply a devm_i8255_regmap_register() function, a configuration

i8255_volatile_regmap_range() provided to simplify volatile PPI register

For the 104-idi-48, we get an IRQ register with some status information
and basic masking, but it's broken down by banks rather than individual
GPIO. There are six banks (8 GPIO lines each) that correspond to the
lower six bits of the IRQ register (bits 0-5):
Base Address + 7 (Read): IRQ Status Register/IRQ Clear
Bit 0-5: Respective Bank IRQ Statuses
Bit 6: IRQ Status (Active Low)
Bit 7: IRQ Enable Status

For the 104-dio-48e we have the following IRQ registers (0xB and 0xF):
Base Address +B (Write): Enable Interrupt
Base Address +B (Read): Disable Interrupt
Base Address +F (Read/Write): Clear Interrupt
Any write to 0xB will enable interrupts, while any read will disable
interrupts. Interrupts are cleared by a write to 0xF. There's no IRQ
status register, so software has to assume that if an interrupt is
raised then it was for the 104-DIO-48E device.

This driver implements a GPIO multiplexer based on latches connected to
other GPIOs. A set of data GPIOs is connected to the data input of
multiple latches. The clock input of each latch is driven by another
set of GPIOs. With two 8-bit latches 10 GPIOs can be multiplexed into
16 GPIOs. GPOs might be a better term as in fact the multiplexed pins
are output only.

Tag (immutable branch) for:
v6.0-rc1 + "[PATCH v6 0/7] add support for another simatic board" series
for merging into the gpio, leds and pdx86 subsystems.
Add GPIO support for Nuvoton NCT6116 chip. Nuvoton SuperIO chips are
very similar to the ones from Fintek. In other subsystems they also
share drivers and are called a family of drivers.
For the GPIO subsystem the only difference is that the direction bit is
reversed and that there is only one data bit per pin. On the SuperIO
level the logical device is another one.
On a chip level we do not have a manufacturer ID to check and also no
revision.

Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8255 Programmable Peripheral
Interface (PPI).
The Intel 8255 PPI first appeared in the early 1970s, initially for the
Intel 8080 and later appearing in the original IBM-PC. The popularity of
the original Intel 8255 chip led to many subsequent variants and clones
of the interface in various chips and integrated circuits. Although
still popular, interfaces compatible with the Intel 8255 PPI are
nowdays typically found embedded in larger VLSI processing chips and
FPGA components rather than as discrete ICs.
A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules
wanting access to these i8255 library functions should select this
Kconfig option, and import the I8255 symbol namespace.
