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" * tag 'gpio-updates-for-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (66 commits) gpio: sim: set a limit on the number of GPIOs gpiolib: protect the GPIO device against being dropped while in use by user-space gpiolib: cdev: fix NULL-pointer dereferences gpiolib: Provide to_gpio_device() helper gpiolib: Unify access to the device properties gpio: Do not include <linux/kernel.h> when not really needed. gpio: pcf857x: Convert to i2c's .probe_new() gpio: pca953x: Convert to i2c's .probe_new() gpio: max732x: Convert to i2c's .probe_new() dt-bindings: gpio: gpio-davinci: Increase maxItems in gpio-line-names gpiolib: ensure that fwnode is properly set gpio: sl28cpld: Replace irqchip mask_invert with unmask_base gpiolib: of: Use correct fwnode for DT-probed chips gpiolib: of: Drop redundant check in of_mm_gpiochip_remove() gpiolib: of: Prepare of_mm_gpiochip_add_data() for fwnode gpiolib: add support for software nodes gpiolib: consolidate GPIO lookups gpiolib: acpi: avoid leaking ACPI details into upper gpiolib layers gpiolib: acpi: teach acpi_find_gpio() to handle data-only nodes gpiolib: acpi: change acpi_find_gpio() to accept firmware node ...
