Pull gpio updates from Bartosz Golaszewski:
"We have lots of small changes all over the place, but no huge reworks
or new drivers:
- use ioread()/iowrite() interfaces instead of raw inb()/outb() in
drivers
- make irqchips immutable due to the new warning popping up when
drivers try to modify the irqchip structures
- add new compatibles to dt-bindings for realtek-otto, renesas-rcar
and pca95xx
- add support for new models to gpio-rcar, gpio-pca953x &
gpio-realtek-otto
- allow parsing of GPIO hogs represented as children nodes of
gpio-uniphier
- define a set of common GPIO consumer strings in dt-bindings
- shrink code in gpio-ml-ioh by using more devres interfaces
- pass arguments to devm_kcalloc() in correct order in gpio-sim
- add new helpers for iterating over GPIO firmware nodes and
descriptors to gpiolib core and use it in several drivers
- drop unused syscon_regmap_lookup_by_compatible() function
- correct format specifiers and signedness of variables in GPIO ACPI
- drop unneeded error checks in gpio-ftgpio
- stop using the deprecated of_gpio.h header in gpio-zevio
- drop platform_data support in gpio-max732x
- simplify Kconfig dependencies in gpio-vf610
- use raw spinlocks where needed to make PREEMPT_RT happy
- fix return values in board files using gpio-pcf857x
- convert more drivers to using fwnode instead of of_node
- minor fixes and improvements in gpiolib core"

We should have 'n', then 'size', not the opposite.
This is harmless because the 2 values are just multiplied, but having
the correct order silence a (unpublished yet) smatch warning.

We need to take mask into account in the set/get_multiple() callbacks.
Use bitmap_replace() instead of bitmap_copy().

Compiler is not happy:
warning: symbol 'gpio_sim_hog_config_item_ops' was not declared. Should it be static?

We always assign the default device name as the chip_label in hog
structures which makes it impossible to assign hogs to chips. Let's
first check if a custom label was set and then copy it instead of the
default device name.

If the user-space sets the chip label to an empty string - we should
check the length and not override the default name or else line hogs
will not be properly attached.

Building with clang returns this error:
gpio-sim.c:889:7: error: variable 'ret' is uninitialized
when used here
ret should be the status of the call to
gpio_sim_make_bank_swnode stored in bank->swnode.

Implement a new, modern GPIO testing module controlled by configfs
attributes instead of module parameters. The goal of this driver is
to provide a replacement for gpio-mockup that will be easily extensible
with new features and doesn't require reloading the module to change
the setup.
