2026-02-04regulator: s2mps11: add S2MPG10 regulatorAndré Draszik
The S2MPG10 PMIC is a Power Management IC for mobile applications with buck converters, various LDOs, power meters, RTC, clock outputs, and additional GPIO interfaces. It has 10 buck and 31 LDO rails. Several of these can either be controlled via software (register writes) or via external signals, in particular by: * one out of several input pins connected to a main processor's: * GPIO pins * other pins that are e.g. firmware- or power-domain-controlled without explicit driver intervention * a combination of input pins and register writes. Control via input pins allows PMIC rails to be controlled by firmware, e.g. during standby/suspend, or as part of power domain handling where otherwise that would not be possible. Additionally toggling a pin is faster than register writes, and it also allows the PMIC to ensure that any necessary timing requirements between rails are respected automatically if multiple rails are to be enabled or disabled quasi simultaneously. This commit implements support for all these rails and control combinations. Additional data needs to be stored for each regulator, e.g. the input pin for external control, or a rail-specific ramp-rate for when enabling a buck-rail. Therefore, probe() is updated slightly to make that possible. Note1: For an externally controlled rail, the regulator_ops provide an empty ::enable() and no ::disable() implementations, even though Linux can not enable the rail and one might think ::enable could be NULL. Without ops->enable(), the regulator core will assume enabling such a rail failed, though, and in turn never add a reference to its parent (supplier) rail. Once a different (Linux-controlled) sibling (consumer) rail on that same parent rail gets disabled, the parent gets disabled (cutting power to the externally controlled rail although it should stay on), and the system will misbehave. Note2: While external control via input pins appears to exist on other versions of this PMIC, there is more flexibility in this version, in particular there is a selection of input pins to choose from for each rail (which must therefore be configured accordingly if in use), whereas other versions don't have this flexibility.

2026-02-04mfd: sec: Add support for S2MPG11 PMIC via ACPMAndré Draszik
Add support for Samsung's S2MPG11 PMIC, which is a Power Management IC for mobile applications with buck converters, various LDOs, power meters, NTC thermistor inputs, and additional GPIO interfaces. It typically complements an S2MPG10 PMIC in a main/sub configuration as the sub-PMIC. Like S2MPG10, communication is not via I2C, but via the Samsung ACPM firmware. While at it, we can also switch to asynchronous probe, which helps with probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in parallel. Note: The firmware uses the ACPM channel ID and the Speedy channel ID to select the PMIC address. Since these are firmware properties, they can not be retrieved from DT, but instead are deducted from the compatible for now.

2026-02-04mfd: sec: s2mpg10: Reorder regulators for better probe performanceAndré Draszik
Bucks can reasonably be supplies for LDOs, but not the other way around. Since rail registration is going to be ordered by 'enum s2mpg10_regulators', it makes sense to specify bucks first, so that during LDO registration it is more likely that the corresponding supply is known already. This can improve probe speed, as no unnecessary deferrals and retries are required anymore.

2026-02-01mfd: wm8350-core: Use IRQF_ONESHOTSebastian Andrzej Siewior
Using a threaded interrupt without a dedicated primary handler mandates the IRQF_ONESHOT flag to mask the interrupt source while the threaded handler is active. Otherwise the interrupt can fire again before the threaded handler had a chance to run. Mark explained that this should not happen with this hardware since it is a slow irqchip which is behind an I2C/ SPI bus but the IRQ-core will refuse to accept such a handler. Set IRQF_ONESHOT so the interrupt source is masked until the secondary handler is done.

2026-01-22mfd: tps65219: Implement LOCK register handling for TPS65214Kory Maincent (TI.com)
The TPS65214 PMIC variant has a LOCK_REG register that prevents writes to nearly all registers when locked. Unlock the registers at probe time and leave them unlocked permanently. This approach is justified because: - Register locking is very uncommon in typical system operation - No code path is expected to lock the registers during runtime - Adding a custom regmap write function would add overhead to every register write, including voltage changes triggered by CPU OPP transitions from the cpufreq governor which could happen quite frequently Cc: stable@vger.kernel.org Fixes: 7947219ab1a2d ("mfd: tps65219: Add support for TI TPS65214 PMIC") Reviewed-by: Andrew Davis <afd@ti.com> Signed-off-by: Kory Maincent (TI.com) <kory.maincent@bootlin.com> Link: https://patch.msgid.link/20251218-fix_tps65219-v5-1-8bb511417f3a@bootlin.com Signed-off-by: Lee Jones <lee@kernel.org>

The ROHM BD72720 is a power management IC which continues the BD71828 family of PMICs. Similarly to the BD71815 and BD71828, the BD72720 integrates regulators, charger, RTC, clock gate and GPIOs. The main difference to the earlier PMICs is that the BD72720 has two different I2C slave addresses. In addition to the registers behind the 'main I2C address', most of the charger (and to some extent LED) control is done via registers behind a 'secondary I2C slave address', 0x4c.

2025-11-20mfd: sec: Use chained IRQs for s2mpg10André Draszik
On S2MPG10 (and similar like S2MPG11), top-level interrupt status and mask registers exist which need to be unmasked to get the PMIC interrupts. This additional status doesn't seem to exist on other PMICs in the S2MP* family, and the S2MPG10 driver is manually dealing with masking and unmasking currently. The correct approach here is to register this hierarchy as chained interrupts, though, without any additional manual steps. Doing so will also simplify addition of other, similar, PMICs (like S2MPG11) in the future. Update the driver to do just that.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "There's one new driver (Apple SMC) and extensions to existing drivers for supporting new HW models. A lot of different impovements across drivers and in core GPIO code. Details on that are in the signed tag as usual. We managed to remove some of the legacy APIs. Arnd Bergmann started to work on making the legacy bits optional so that we may compile them only for older platforms that still really need them. Rob Herring has done a lot of work to convert legacy .txt dt-bindings for GPIO controllers to YAML. There are only a few left now in the GPIO tree. A big part of the commits in this PR concern the conversion of GPIO drivers to using the new line value setter callbacks. This conversion is now complete treewide (unless I've missed something) and once all the changes from different trees land in mainline, I'll send you another PR containing a commit dropping the legacy callbacks from the tree. As the quest to pay back technical dept never really ends, we're starting another set of interface conversions, this time it's about moving fields specific to only a handful of drivers using the gpio-mmio helper out of the core gpio_chip structure that every controller implements and uses. This cycle we introduce a new set of APIs and convert a few drivers under drivers/gpio/, next cycle we'll convert remaining modules treewide (in gpio, pinctrl and mfd trees) and finally remove the old interfaces and move the gpio-mmio fields into their own structure wrapping gpio_chip. One last change I should mention here is the rework of the sysfs interface. In 2016, we introduced the GPIO character device as the preferred alternative to the sysfs class under /sys/class/gpio. While it has seen a wide adoption with the help of its user-space counterpart - libgpiod - there are still users who prefer the simplicity of sysfs. As far as the GPIO subsystem is concerned, the problem is not the existince of the GPIO class as such but rather the fact that it exposes the global GPIO numbers to the user-space, stopping us from ever being able to remove the numberspace from the kernel. To that end, this release we introduced a parallel, limited sysfs interface that doesn't expose these numbers and only implements a subset of features that are relevant to the existing users. This is a result of several discussions over the course of last year and should allow us to remove the legacy part some time in the future. Summary: GPIOLIB core: - introduce a parallel, limited sysfs user ABI that doesn't expose the global GPIO numbers to user-space while maintaining backward compatibility with the end goal of it completely replacing the existing interface, allowing us to remove it - remove the legacy devm_gpio_request() routine which has no more users - start the process of allowing to compile-out the legacy parts of the GPIO core for users who don't need it by introducing a new Kconfig option: GPIOLIB_LEGACY - don't use global GPIO numbers in debugfs output from the core code (drivers still do it, the work is ongoing) - start the process of moving the fields specific to the gpio-mmio helper out of the core struct gpio_chip into their own structure that wraps it: create a new header with modern interfaces and convert several drivers to using it - remove the platform data structure associated with the gpio-mmio helper from the kernel after having converted all remaining users to generic device properties - remove legacy struct gpio definition as it has no more users New drivers: - add the GPIO driver for the Apple System Management Controller Driver improvements: - add support for new models to gpio-adp5585, gpio-tps65219 and gpio-pca953x - extend the interrupt support in gpio-loongson-64bit - allow to mark the simulated GPIO lines as invalid in gpio-sim - convert all remaining GPIO drivers to using the new GPIO value setter callbacks - convert gpio-rcar to using simple device power management ops callbacks - don't check if current direction of a line is output before setting the value in gpio-pisosr and ti-fpc202: the GPIO core already handles that - also drop unneeded GPIO range checks in drivers, the core already makes sure we're within bounds when calling driver callbacks - use dev_fwnode() where applicable across GPIO drivers - set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user wants to change direction of the pin to output even though these drivers don't need to do anything else to actually set the direction, otherwise a call like gpiod_direction_output(d, 1) will not result in the line driver high - remove the reduntant call to pm_runtime_mark_last_busy() from gpio-arizona - use lock guards in gpio-cadence and gpio-mxc - check the return values of regmap functions in gpio-wcd934x and gpio-tps65912 - use better regmap interfaces in gpio-wcove and gpio-pca953x - remove dummy GPIO chip callbacks from several drivers in cases where the GPIO core can already handle their absence - allow building gpio-palmas as a module Fixes: - use correct bit widths (according to the documentation) in gpio-virtio Device-tree bindings: - convert several of the legacy .txt documents for many different devices to YAML, improving automatic validation - create a "trivial" GPIO DT schema that covers a wide range of simple hardware that share a set of basic GPIO properties - document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander - document a new model for pca95xx - add and/or remove properties in YAML documents for gpio-rockchip, fsl,qoriq-gpio, arm,pl061 and gpio-xilinx Misc: - some minor refactoring in several places, adding/removing forward declarations, moving defines to better places, constify the arguments in some functions, remove duplicate includes, etc. - documentation updates" * tag 'gpio-updates-for-v6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (202 commits) MIPS: alchemy: gpio: use new GPIO line value setter callbacks for the remaining chips gpiolib: enable CONFIG_GPIOLIB_LEGACY even for !GPIOLIB gpio: virtio: Fix config space reading. gpiolib: make legacy interfaces optional dt-bindings: gpio: rockchip: Allow use of a power-domain gpiolib: of: add forward declaration for struct device_node power: reset: macsmc-reboot: Add driver for rebooting via Apple SMC gpio: Add new gpio-macsmc driver for Apple Macs mfd: Add Apple Silicon System Management Controller soc: apple: rtkit: Make shmem_destroy optional dt-bindings: mfd: Add Apple Mac System Management Controller dt-bindings: power: reboot: Add Apple Mac SMC Reboot Controller dt-bindings: gpio: Add Apple Mac SMC GPIO block gpio: cadence: Remove duplicated include in gpio-cadence.c gpio: tps65219: Add support for TI TPS65214 PMIC gpio: tps65219: Update _IDX & _OFFSET macro prefix gpio: sysfs: Fix an end of loop test in gpiod_unexport() dt-bindings: gpio: Convert qca,ar7100-gpio to DT schema dt-bindings: gpio: Convert maxim,max3191x to DT schema dt-bindings: gpio: fsl,qoriq-gpio: Add missing mpc8xxx compatibles ...

2025-07-24mfd: rk8xx-core: Allow to customize RK806 reset modeQuentin Schulz
The RK806 PMIC has a bitfield for configuring the restart/reset behavior (which I assume Rockchip calls "function") whenever the PMIC is reset either programmatically (c.f. DEV_RST in the datasheet) or via PWRCTRL or RESETB pins. For RK806, the following values are possible for RST_FUN: 0b00 means "Restart PMU" 0b01 means "Reset all the power off reset registers, forcing the state to switch to ACTIVE mode" 0b10 means "Reset all the power off reset registers, forcing the state to switch to ACTIVE mode, and simultaneously pull down the RESETB PIN for 5mS before releasing" 0b11 means the same as for 0b10 just above. This adds the appropriate logic in the driver to parse the new rockchip,reset-mode DT property to pass this information. It just happens that the values in the binding match the values to write in the bitfield so no mapping is necessary. If it is missing, the register is left untouched and relies either on the silicon default or on whatever was set earlier in the boot stages (e.g. the bootloader).

2025-07-24mfd: Add Apple Silicon System Management ControllerSven Peter
The System Management Controller (SMC) on Apple Silicon machines is a piece of hardware that exposes various functionalities such as temperature sensors, voltage/power meters, shutdown/reboot handling, GPIOs and more. Communication happens via a shared mailbox using the RTKit protocol which is also used for other co-processors. The SMC protocol then allows reading and writing many different keys which implement the various features. The MFD core device handles this protocol and exposes it to the sub-devices. Some of the sub-devices are potentially also useful on pre-M1 Apple machines and support for SMCs on these machines can be added at a later time.

When KCOV is enabled all functions get instrumented, unless the __no_sanitize_coverage attribute is used. To prepare for __no_sanitize_coverage being applied to __init functions, we have to handle differences in how GCC's inline optimizations get resolved. For arm this exposed several places where __init annotations were missing but ended up being "accidentally correct". Fix these cases and force several functions to be inline with __always_inline.

2025-07-10mfd: tps6594: Add TI TPS652G1 supportMichael Walle
The TPS652G1 is a stripped down version of the TPS65224. From a software point of view, it lacks any voltage monitoring, the watchdog, the ESM and the ADC.

2025-07-01gpio: adp5585: support gpi eventsNuno Sá
Add support for adding GPIs to the event FIFO. This is done by adding irq_chip support. Like this, one can use the input gpio_keys driver as a "frontend" device and input handler. As part of this change, we now implement .request() and .free() as we can't blindly consume all available pins as GPIOs (example: some pins can be used for forming a keymap matrix). Also note that the number of pins can now be obtained from the parent, top level device. Hence the 'max_gpio' variable can be removed.
