2026-05-24regulator: add support for SGM3804 Dual Output driverMark Brown

The SGM3804 is powered by the enable GPIO pins inputs and only supports I2C write messages. In order to add flexibility and simplify the driver, the regmap cache is enabled and populated with default values since we can't write registers when the 2 GPIOs are down. This regulator is used to provide vsn and vsn power to the Ayaneo Pocket S2 dual-DSI LCD panel.

2026-03-24regulator: da91xx: Allow caching of buck registers when no GPIO input ↵Mark Brown
control is configured André Svensson <andre.svensson@axis.com> says: This series introduces a boolean DT property, dlg,no-gpio-control, for the DA91xx regulators. Use this property to indicate that GPIO control is not configured with the functions DVC/RELOAD/EN, allowing buck registers to be cached. The DA9121 driver checks dlg,no-gpio-control and updates regmap_config's volatile_table if the property is present. Buck registers are removed from the volatile_table if the property is present, enabling caching of the registers, which removes I2C reads when performing an I2C write to the buck registers.

2026-03-24regulator: dt-bindings: dlg,da9121: Add dlg,no-gpio-controlAndré Svensson
Add the optional boolean property dlg,no-gpio-control. When present, it indicates that no DA91xx GPIO pins are configured/used with functions RELOAD/DVC/EN, which can affect the output voltage control, regulator mode control and enable signal control. The absence of relevant GPIO DT properties does not imply that the RELOAD/DVC/EN GPIO functions are unused. These functions are provided by DA91xx GPIO pins and may be controlled by external hardware without corresponding GPIO DT properties. The dlg,no-gpio-control property explicitly indicates that none of these GPIO functions are used. It is mutually exclusive with enable-gpios, regardless of whether the referenced GPIO is connected to a GPIO pin or the IC_EN pin, since enable-gpios allows the regulator to be controlled via an external hardware signal.

Robby Cai <robby.cai@nxp.com> says: The FP9931 regulator requires a valid "vin" supply to operate correctly. Therefore, the driver should treat "vin" as a mandatory supply.

As suggested in the reviews from Andreas and Mark, v2 switches to using devm_regulator_get() since the supply is mandatory.

Merge series from Franz Schnyder <franz.schnyder@toradex.com>: The IRQ_B pin is an open-drain output. The datasheet specifies, that the IRQ_B pin is pulled low when any unmasked interrupt bit status is changed, and it is released high once the application processor reads the INT1 register. As it specifies a level-low behavior, it should not force a falling-edge interrupt. Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt and instead rely on the flag from the device tree. Set the IRQF_SHARED to be able to share the interrupt line with other devices. If the interrupt has not been triggered by the PMIC, return IRQ_NONE.

Merge series from André Draszik <andre.draszik@linaro.org>: This series extends the existing S2MPG10 PMIC driver to add support for the regulators, and adds new S2MPG11 core and regulator drivers. The patches are kept together in one series, due to S2MPG11 and its regulators being very similar to S2MPG10. The Samsung S2MPG11 PMIC is a Power Management IC for mobile applications with buck converters, various LDOs, power meters, and additional GPIO interfaces. It typically complements an S2MPG10 PMIC in a main/sub configuration as the sub-PMIC and both are used on the Google Pixel 6 and 6 Pro (oriole / raven). A DT update for Oriole / Raven to enable these is required which I will send out separately.
2026-02-04regulator: dt-bindings: add s2mpg11-pmic regulatorsAndré Draszik
The S2MPG11 PMIC 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. S2MPG11 has 12 buck, 1 buck-boost, and 15 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. 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. Add documentation related to the regulator (buck & ldo) parts like devicetree definitions, regulator naming patterns, and additional properties. Since S2MPG11 is typically used as the sub-PMIC together with an S2MPG10 as the main-PMIC, the datasheet and the binding both suffix the rails with an 's'.

2026-01-13dt-bindings: regulator: ROHM BD72720Matti Vaittinen
The ROHM BD72720 is a new PMIC with 10 BUCk and 11 LDO regulators. The BD72720 is designed to support using the BUCK10 as a supply for the LDOs 1 to 4. When the BUCK10 is used for this, it can be set to a LDON_HEAD mode. In this mode, the BUCK10 voltage can't be controlled by software, but the voltage is adjusted by PMIC to match the LDO1 .. LDO4 voltages with a given offset. Offset can be 50mV .. 300mV and is changeable at 50mV steps. Add 'ldon-head-microvolt' property to denote a board which is designed to utilize the LDON_HEAD mode. All other properties are already existing. Add dt-binding doc for ROHM BD72720 regulators to make it usable.

2026-01-13regulator: Add TPS65185Mark Brown
Merge series from Andreas Kemnade <andreas@kemnade.info>: Add a driver for the TPS65185 regulator which provides the comparatively high voltages needed for electronic paper displays. Datasheet for the TPS65185 is at https://www.ti.com/lit/gpn/tps65185 To simplify things, include the hwmon part directly which is only one temperature sensor and there are no other functions besides regulators in this chip.

Document the TPS65185. GPIO names are same as in the datasheet except for the PWRUP pad which is described as "enable". That pin is optional because the rising edge corresponds to setting one register bit and falling edge to another register bit.

2025-11-06Add support MT6316/6363/MT6373 PMICs regulatorsMark Brown
Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>: This series adds support for three new MediaTek PMICs: MT6316, MT6363 and MT6373 and their variants - used in board designs featuring the MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone SoC. 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.
