Merge tag 'gpio-updates-for-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have some new drivers, significant refactoring of existing intel
platforms, lots of improvements all around, mass conversion to using
immutable irqchips by drivers that had not been converted individually
yet and some changes in the core library code.
Summary:
New drivers:
- add a driver for the Loongson GPIO controller
- add a driver for the fxl6408 I2C GPIO expander
- add a GPIO module containing code common for Intel Elkhart Lake and
Merrifield platforms
- add a driver for the Intel Elkhart Lake platform reusing the code
from the intel tangier library
GPIOLIB core:
- GPIO ACPI improvements
- simplify gpiochip_add_data_with_keys() fwnode handling
- cleanup header inclusions (remove unneeded ones, order the rest
alphabetically)
- remove duplicate code (reuse krealloc() instead of open-coding it,
drop a duplicated check in gpiod_find_and_request())
- reshuffle the code to remove unnecessary forward declarations
- coding style cleanups and improvements
- add a helper for accessing device fwnodes
- small updates in docs
Driver improvements:
- convert all remaining GPIO irqchip drivers to using immutable
irqchips
- drop unnecessary of_match_ptr() macro expansions
- shrink the code in gpio-merrifield significantly by reusing the
code from gpio-tangier + minor tweaks to the driver code
- remove MODULE_LICENSE() from drivers that can only be built-in
- add device-tree support to gpio-loongson1
- use new regmap features in gpio-104-dio-48e and gpio-pcie-idio-24
- minor tweaks and fixes to gpio-xra1403, gpio-sim, gpio-tegra194,
gpio-omap, gpio-aspeed, gpio-raspberrypi-exp
- shrink code in gpio-ich and gpio-pxa
- Kconfig tweak for gpio-pmic-eic-sprd"
