Merge tag 'gpio-updates-for-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have a new GPIO multiplexer driver, bunch of driver updates and
refactoring in the core GPIO library.
GPIO core:
- teach gpiolib to work with software nodes for HW description
- remove ARCH_NR_GPIOS treewide as we no longer impose any limit on
the number of GPIOS since the allocation became entirely dynamic
- add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC
controller, Freescale PCIe and Ethernet controller, Himax LCDs and
Mediatek mt2701
- refactor OF quirk code
- some general refactoring of the OF and ACPI code, adding new
helpers, minor tweaks and fixes, making fwnode usage consistent
etc.
GPIO uAPI:
- fix an issue where the user-space can trigger a NULL-pointer
dereference in the kernel by opening a device file, forcing a
driver unbind and then calling one of the syscalls on the
associated file descriptor
New drivers:
- add gpio-latch: a new GPIO multiplexer based on latches connected
to other GPIOs
Driver updates:
- convert i2c GPIO expanders to using .probe_new()
- drop the gpio-sta2x11 driver
- factor out common code for the ACCES IDIO-16 family of controllers
and use this new library wherever applicable in drivers
- add DT support to gpio-hisi
- allow building gpio-davinci as a module and increase its maxItems
property
- add support for a new model to gpio-pca9570
- other minor changes to various drivers"
