Merge tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski: "We have two new drivers, some improvements to the core code, lots of different updates to existing GPIO drivers and some dt-bindings on top. There's nothing controversial in here and almost everything has been in next for more than a week (95% a lot longer than this). The only thing that has spent less time in next is a new driver so no risk of regressions. The single merge pulls in changes that remove all usage of global GPIO numbers from arch/arm/mach-omap. Core GPIO library: - remove unused symbols - don't spam the kernel log with messages about hogs - remove old sysfs API cruft - improve handling of GPIO masks New drivers: - add a driver for the BlueField-3 GPIO controller - add GPIO support for the TPS65219 PMIC Driver improvements: - extend the gpio-aggregator driver to support ramp-up/ramp-down delay - remove unnecessary CONFIG_OF guards from gpio-aggregator - readability improvements in gpio-tangier - switch i2c drivers back to using probe() now that it's been converted in the i2c subsystem to not taking the id parameter - remove unused inclusions of of_gpio.h in several drivers - make pm ops static in gpio-davinci and fix a comment - use more devres in drivers to shrink and simplify the code - add missing include in gpio-sa1100 - add HAS_IOPORT KConfig dependency where needed - add permissions checks before accessing pins in gpio-tegra186 - convert the gpio-zynq driver to using immutable irqchips - preserve output settings set by the bootloader in gpio-mpc8xxx Selftests: - tweak the variable naming in script tests Device tree updates: - convert gpio-mmio and gpio-stmpe to YAML - add parsing of GPIO hogs to gpio-vf610 - add bindings for the Cirrus EP93xx GPIO controller - add gpio-line-names property to the gpio-pca9570 bindings - extend the binding for x-powers,axp209 with another block" * tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (58 commits) of: unittest: drop assertions for GPIO hog messages gpiolib: Drop unused domain_ops memeber of GPIO IRQ chip gpio: synq: remove unused zynq_gpio_irq_reqres/zynq_gpio_irq_relres dt-bindings: gpio: gpio-vf610: Add parsing of hogs gpio: lpc18xx: Remove unused of_gpio.h inclusion gpio: xra1403: Remove unused of_gpio.h inclusion gpio: mpc8xxx: Remove unused of_gpio.h inclusion dt-bindings: gpio: Add Cirrus EP93xx gpio: mpc8xxx: latch GPIOs state on module load when configured as output selftests: gpio: gpio-sim: Use same variable name for sysfs pathname gpio: mlxbf3: Add gpio driver support gpio: delay: Remove duplicative functionality gpio: aggregator: Set up a parser of delay line parameters gpio: aggregator: Support delay for setting up individual GPIOs gpio: aggregator: Remove CONFIG_OF and of_match_ptr() protections dt-bindings: gpio: pca9570: add gpio-line-names property gpiolib: remove unused gpio_cansleep() gpio: tps65219: add GPIO support for TPS65219 PMIC gpio: zynq: fix zynqmp_gpio not an immutable chip warning gpio: davinci: make davinci_gpio_dev_pm_ops static ...
