gpio: mmio: do not calculate bgpio_bits via "ngpios"

[ Upstream commit f07798d7bb9c46d17d80103fb772fd2c75d47919 ]

bgpio_bits must be aligned with the data bus width. For example, on a
32 bit big endian system and we only have 16 GPIOs. If we only assume
bgpio_bits=16 we can never control the GPIO because the base address
is the lowest address.

Merge tag 'gpio-updates-for-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
"We have a lot of code refactoring using common helpers and ended up
removing more lines then we're adding this release cycle.

Nothing really stands out, just small updates all over the place.

Core GPIOLIB updates:
- wake-up poll() in user-space on device unbind
- improve fwnode usage
- interrupt domain handling improvements
- correctly handle the ngpios property in gpio-mmio

Driver cleanups:
- remove unneeded calls to platform_set_drvdata() all around the
place
- remove unneeded of_match_ptr() expansions whenever a driver depends
on CONFIG_OF
- remove redundant calls to dev_err_probe() from gpio-omap and
gpio-davinci

Driver improvements:
- use autopointers and guards from cleanup.h in gpio-sim
- shrink code in gpio-sim using some common helpers
- convert the idio family of drivers to using gpio-regmap
- convert gpio-ws16c48 to using gpio-regmap
- use devres to simplify code in gpio-pisosr and gpio-mxc
- update gpio-sifive: support IRQ wake, improve interrupt handling,
allow building as module
- make gpio-ge and gpio-bcm-kona OF-independent (plus some minor
tweaks)
- add support for new models in gpio-pca953x and gpio-ds4520
- add runtime PM support to gpio-mxc
- fix a build warning in gpio-mxs
- add support for adding pin ranges to gpio-mlxbf3
- add counter/timer support to gpio-104-dio-48e
- switch to dynamic GPIO base allocation in gpio-vf610
- minor oneliners here and there

Device-tree bindings updates:
- enable the gpio-line-names property in snps,dw-apb and STMPE GPIO
- document new models in fsl-imx-gpio, ds4520 and pca95xx
- convert the bindings for brcm,kona-gpio to YAML"

gpio: mmio: handle "ngpios" properly in bgpio_init()

bgpio_init() uses "sz" argument to populate ngpio, which is not
accurate. Instead, read the "ngpios" property from the DT and if it
doesn't exist

gpio: mmio: handle "ngpios" properly in bgpio_init()

bgpio_init() uses "sz" argument to populate ngpio, which is not
accurate. Instead, read the "ngpios" property from the DT and if it
doesn't exist, use the "sz" argument. With this change, drivers no
longer need to overwrite the ngpio variable after calling bgpio_init().

If the "ngpios" property is specified, bgpio_bits is calculated
as the round up value of ngpio. At the moment, the only requirement
specified is that the round up value must be a multiple of 8 but
it should also be a power of 2 because we provide accessors based
on the bank size in bgpio_setup_accessors().

"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"
