2026-02-05Samsung S2MPG10 regulator and S2MPG11 PMIC driversMark Brown
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.

2025-10-15regulator: dt-bindings: rpmh-regulator: Update pmic-id DT prop info for new ↵Kamal Wadhwa
CMD-DB Currently, CMD-DB names for RPMH regulators follow this format: `^(smps|ldo|bob|vs)[a-n][1-9][0-9]?$` Here, the `[a-n]` value is read from the `pmic-id` DT property, which is unique to each PMIC present on the board. Note that in this older CMD-DB name format the SPMI bus on which a particular PMIC regulator exists was not apparent from its CMD-DB name. New targets like Glymur, where we have multiple SPMI buses, overcome this limitation by following a new CMD-DB name format: `^(L|S|B)[1-9][0-9]?[A-N]_E[0-3]$` Here `[A-N]_E[0-3]` part will now be read from the `pmic-id` DT prop and it includes the SPMI bus id `[0-3]` as well. However, the PMIC ID part `[A-N]` of the CMD-DB name is now unique only to the SPMI bus that the PMIC regulator is present on. which means `L1B_E0` and `L1B_E1` are both possible CMD-DB names for two different regulator LDOs present on two different SPMI buses (bus id 0 and 1) on the same board. Note that since the new `pmic-id` DT property is a combo of PMIC ID and SPMI bus ID, so its still unique to each PMIC present on the board. Update the `pmic-id` property pattern information to reflect this change in the driver handling to support this new CMD-DB naming format while maintaining backward compatiblilty with old CMD-DB naming format which is still supported for older/existing targets.
