Merge tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linuxPull gpio updates from Bartosz Golaszewski: "For this merge window we have two new drivers: support for GPIO-signalled ACPI events on Intel platforms and a generic GPIO-over-pinctrl driver using the ARM SCMI protocol for controlling pins. Several things have been reworked in GPIO core: we unduplicated GPIO hog handling, reduced the number of SRCU locks and dereferences, improved support for software-node-based lookup and removed more legacy code after converting remaining users to modern alternatives. There's also a number of driver reworks and refactoring, documentation updates, some bug-fixes and new tests. GPIO core: - defer probe on software node lookups when the remote software node exists but has not been registered as a firmware node yet - unify GPIO hog handling by moving code duplicated in OF and ACPI modules into GPIO core and allow setting up hogs with software nodes - allow matching GPIO controllers by secondary firmware node if matching by primary does not succeed - demote deferral warnings to debug level as they are quite normal when using software nodes which don't support fw_devlink yet - disable the legacy GPIO character device uAPI v1 supprt in Kconfig by default - rework several core functions in preparation for the upcoming Revocable helper library for protecting resources against sudden removal, this reduces the number of SRCU dereferences in GPIO core - simplify file descriptor logic in GPIO character device code by using FD_PREPARE() - introduce a header defining symbols used by both GPIO consumers and providers to avoid having to include provider-specific headers from drivers which only consume GPIOs - replace snprintf() with strscpy() where formatting is not required New drivers: - add the gpio-by-pinctrl generic driver using the ARM SCMI protocol to control GPIOs (along with SCMI changes pulled from the pinctrl tree) - add a driver providing support for handling of platform events via GPIO-signalled ACPI events (used on Intel Nova Lake and later platforms) Driver changes: - extend the gpio-kempld driver with support for more recent models, interrupts and setting/getting multiple values at once - improve interrupt handling in gpio-brcmstb - add support for multi-SoC systems in gpio-tegra186 - make sure we return correct values from the .get() callbacks in several GPIO drivers by normalizing any values other than 0, 1 or negative error numbers - use flexible arrays in several drivers to reduce the number of required memory allocations - simplify synchronous waiting for virtual drivers to probe and remove the dedicated, a bit overengineered helper library dev-sync-probe - remove unneeded Kconfig dependencies on OF_GPIO in several drivers and subsystems - convert the two remaining users of of_get_named_gpio() to using GPIO descriptors and remove the (no longer used) function along with the header that declares it - add missing includes in gpio-mmio - shrink and simplify code in gpio-max732x by using guard(mutex) - remove duplicated code handling the 'ngpios' property from gpio-ts4800, it's already handled in GPIO core - use correct variable type in gpio-aspeed - add support for a new model in gpio-realtek-otto - allow to specify the active-low setting of simulated hogs over the configfs interface (in addition to existing devicetree support) in gpio-sim Bug fixes: - clear the OF_POPULATED flag on hog nodes in GPIO chip remove path on OF systems - fix resource leaks in error path in gpiochip_add_data_with_key() - drop redundant device reference in gpio-mpsse Tests: - add selftests for use-after-free cases in GPIO character device code DT bindings: - add a DT binding document for SCMI based, gpio-over-pinctrl devices - fix interrupt description in microchip,mpfs-gpio - add new compatible for gpio-realtek-otto - describe the resets of the mpfs-gpio controller - fix maintainer's email in gpio-delay bindings - remove the binding document for cavium,thunder-8890 as the corresponding device is bound over PCI and not firmware nodes Documentation: - update the recommended way of converting legacy boards to using software nodes for GPIO description - describe GPIO line value semantics - misc updates to kerneldocs Misc: - convert OMAP1 ams-delta board to using GPIO hogs described with software nodes"* tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (79 commits) gpio: swnode: defer probe on references to unregistered software nodes dt-bindings: gpio: cavium,thunder-8890: Remove DT binding Documentation: gpio: update the preferred method for using software node lookup gpio: gpio-by-pinctrl: s/used to do/is used to do/ gpio: aspeed: fix unsigned long int declaration gpio: rockchip: convert to dynamic GPIO base allocation gpio: remove dev-sync-probe gpio: virtuser: stop using dev-sync-probe gpio: aggregator: stop using dev-sync-probe gpio: sim: stop using dev-sync-probe gpio: Add Intel Nova Lake ACPI GPIO events driver gpiolib: Make deferral warnings debug messages gpiolib: fix hogs with multiple lines gpio: fix up CONFIG_OF dependencies gpio: gpio-by-pinctrl: add pinctrl based generic GPIO driver gpio: dt-bindings: Add GPIO on top of generic pin control firmware: arm_scmi: Allow PINCTRL_REQUEST to return EOPNOTSUPP pinctrl: scmi: ignore PIN_CONFIG_PERSIST_STATE pinctrl: scmi: Delete PIN_CONFIG_OUTPUT_IMPEDANCE_OHMS support pinctrl: scmi: Add SCMI_PIN_INPUT_VALUE ...

Wed, 18 Mar 2026 12:04:33 +0100

gpio: mpfs: Add interrupt supportAdd support for interrupts to the PolarFire SoC GPIO driver. Each GPIOhas an independent interrupt that is wired to an interrupt mux that sitsbetween the controllers and the PLIC. The SoC has more GPIO lines thanconnections from the mux to the PLIC, so some GPIOs must share PLICinterrupts. The configuration is not static and is set at runtime,conventionally by the platform's firmware. CoreGPIO, the versionintended for use in the FPGA fabric has two interrupt output ports, oneis IO_NUM bits wide, as is used in the hardened cores, and the other isa single bit with all lines ORed together.Acked-by: Bartosz Golaszewski Reviewed-by: Linus Walleij Signed-off-by: Conor Dooley List of files: /linux/drivers/gpio/Kconfig

gpio: kempld: Implement the interrupt controllerAdd a GPIO IRQ chip implementation for the kempld GPIO controller. Ofnote is only how the parent IRQ is obtained.The IRQ for the GPIO controller can be configured in the BIOS, alongwith the IRQ for the I2C controller. These IRQ are returned by ACPIbut this information is only usable if both IRQ are configured. Whenonly one is configured, only one is returned making it impossible toknow which one it is.Luckily the BIOS will set the configured IRQ in the PLD registers, soit can be read from there instead, and that also work on platformswithout ACPI.The vendor driver allowed to override the IRQ using a moduleparameters, so there are boards in field which used this parameterinstead of properly configuring the BIOS. This implementation providesthis as well for compatibility.Signed-off-by: Alban Bedel Link: https://patch.msgid.link/20260311143120.2179347-5-alban.bedel@lht.dlh.deSigned-off-by: Bartosz Golaszewski List of files: /linux/drivers/gpio/Kconfig
