git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull 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 ...

ROHM BD72720 is a power management IC which integrates 10 buck and 11 LDO regulators. This PMIC has plenty of commonalities with the BD71828 and BD71879. The BD72720 does also have similar 'run-level'-concept as the BD71828 had. It allows controlling the regulator's 'en masse', although only BUCK1 and LDO1 can utilize this in BD72720. Similar to BD71828, this 'en masse' -control is not supported by this driver. Support the voltage and enable/disable state control for the BD72720.

2026-01-12regulator: Add TPS65185 driverAndreas Kemnade
Add a driver for the TPS65185 regulator. Implement handling of the various gpio pins. Because the PWRUP (=enable) pin functionality can be achieved by just using two bits instead, just ensure that it is set to a stable value. Implement the pair of symmetric LDOs as a single regulator because they share a single voltage set register. As the VCOM regulator sits behind that machinery, just define that one as a supply. For simplicity, just add the temperature sensor (depending on external NTC) directly. There is a mechanism to measure some kick-back voltage during a defined EPD operation, to calibrate the VCOM voltage setting and store that non-volatile in the chip to be the power up default setup. That is not implemented yet in the driver, but that also means that there is a non-factory default value in these registers after power-up.

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>: Use container_of_const(), which is preferred over container_of(), when the argument 'ptr' and returned pointer are already const, for better code safety and readability.

2025-11-20regulator: Add FP9931/JD9930 driverAndreas Kemnade
Add a driver for the FP9931/JD9930 regulator. Implement handling of the PG (power good), TS_EN (temperature sensor enable), and EN (enable regulators) pins. Implement the pair of symmetric LDOs as a single regulator because they share a single voltage set register. For simplicity, just add the temperature sensor (depending on external NTC) directly. Limitations: - As these regulators are controlled together with the VCOM regulator via the EN pin, some kind of management must be in place. As the enable op is not called when the regulator is already enabled, simple refcounting seems not to work to avoid clearing EN when one regulator is still enabled. As these regulators are typically used together, this limitation should not hurt hard, just provide the is_enabled op. - As the VCOM step is quite odd (5V/255 steps), rounding is needed. Due to some limitations in the regulator core, the max/min voltages in the devicetree must match the idea of the driver how to round things exactly. - Night mode is not implemented, so only the FP9931 compatible is needed in the driver, there is no REGULATOR_MODE_NIGHT and no clear definition in the datasheet what it does, also the XON pin which seems to be an input related to that night mode is not used.

In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs are multi-function devices, as they have and expose multiple sub-devices; moreover, some of those also contain an interrupt controller, managing internal IPs interrupts: for those, a chained interrupt handler is registered, which parent is the SPMI controller itself. This series adds support for all of the MT6316 regulator variants and for MT6363, MT6373 SPMI PMICs and their interrupt controller.

Isolate all changes involving TPS65215 regulator desc and range resources. - 'chipid' will identify which PMIC to support, and the corresponding chip_data struct element to use in probe(). The chip_data struct is helpful for any new PMICs added to this driver. The goal is to add future PMIC info to necessary structs and minimize probe() function edits. - The probe() will now loop through common (overlapping) regulators first, then device-specific structs identified in the chip_data struct. - Add TI TPS65215 PMIC to the existing platform_device_id struct, so the regulator probe() can handle which PMIC chip_data information to use.
