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 ...

gpio: Support ROHM BD72720 gpiosThe ROHM BD72720 has 6 pins which may be configured as GPIOs. TheGPIO1 ... GPIO5 and EPDEN pins. The configuration is done to OTP at themanufacturing, and it can't be read at runtime. The device-tree isrequired to tell the software which of the pins are used as GPIOs.Keep the pin mapping static regardless the OTP. This way the user-spacecan always access the BASE+N for GPIO(N+1) (N = 0 to 4), and BASE + 5for the EPDEN pin. Do this by setting always the number of GPIOs to 6,and by using the valid-mask to invalidate the pins which aren't configuredas GPIOs.First two pins can be set to be either input or output by OTP. Directioncan't be changed by software. Rest of the pins can be set as outputsonly. All of the pins support generating interrupts.Support the Input/Output state getting/setting and the output modeconfiguration (open-drain/push-pull).Signed-off-by: Matti Vaittinen Reviewed-by: Linus Walleij Acked-by: Bartosz Golaszewski Link: https://patch.msgid.link/22e095ca92f0677ca3d3a768ad749629fc3c2006.1765804226.git.mazziesaccount@gmail.comSigned-off-by: Lee Jones List of files: /linux/drivers/gpio/Makefile

2b03d9a40cd1fea42fd65d2b66df80edc0f374c8 - gpio: add gpio-line-mux driver

Sat, 27 Dec 2025 19:01:34 +0100

gpio: add gpio-line-mux driverAdd a new driver which provides a 1-to-many mapping for a single realGPIO using a multiplexer. Each virtual GPIO corresponds to a multiplexerstate which, if set for the multiplexer, connects the real GPIO to thecorresponding virtual GPIO.This can help in various usecases. One practical case is the specialhardware design of the Realtek-based XS1930-10 switch from Zyxel. Itfeatures two SFP+ ports/cages whose signals are wired directly to theswitch SoC. Although Realtek SoCs are short on GPIOs, there are usuallyenough the fit the SFP signals without any hacks.However, Zyxel did some weird design and connected RX_LOS, MOD_ABS andTX_FAULT of one SFP cage onto a single GPIO line controlled by amultiplexer (the same for the other SFP cage). The single multiplexercontrols the lines for both SFP and depending on the state, thedesignated 'signal GPIO lines' are connected to one of the three SFPsignals.Because the SFP core/driver doesn't support multiplexer but needs singleGPIOs for each of the signals, this driver fills the gap between both.It registers a gpio_chip, provides multiple virtual GPIOs and sets thebacking multiplexer accordingly.Due to several practical issues, this is input-only and doesn't supportIRQs.Signed-off-by: Jonas Jelonek Reviewed-by: Thomas Richard Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/20251227180134.1262138-3-jelonek.jonas@gmail.comSigned-off-by: Bartosz Golaszewski List of files: /linux/drivers/gpio/Makefile
