Merge tag 'gpio-updates-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
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" * tag 'gpio-updates-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (55 commits) gpio: sifive: Make the irqchip immutable gpio: rcar: Make the irqchip immutable gpio: pcf857x: Make the irqchip immutable gpio: pca953x: Make the irqchip immutable gpio: dwapb: Make the irqchip immutable gpio: sim: Use correct order for the parameters of devm_kcalloc() gpio: ml-ioh: Convert to use managed functions pcim* and devm_* gpio: ftgpio: Remove unneeded ERROR check before clk_disable_unprepare gpio: ws16c48: Utilize iomap interface gpio: gpio-mm: Utilize iomap interface gpio: 104-idio-16: Utilize iomap interface gpio: 104-idi-48: Utilize iomap interface gpio: 104-dio-48e: Utilize iomap interface gpio: zevio: drop of_gpio.h header gpio: max77620: Make the irqchip immutable dt-bindings: gpio: pca95xx: add entry for pca6408 gpio: pca953xx: Add support for pca6408 gpio: max732x: Drop unused support for irq and setup code via platform data gpio: vf610: drop the SOC_VF610 dependency for GPIO_VF610 gpio: syscon: Remove usage of syscon_regmap_lookup_by_compatible ...
