2025-11-26regulator: Use container_of_const() when all types areMark Brown
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. Some drivers already have const everywhere, so container_of_const can be directly used. In few other drivers, the final pointer can be constified that way.
2025-11-21regulator: Add FP9931/JD9930Mark Brown
Merge series from Andreas Kemnade <andreas@kemnade.info>: Add a driver for the FP9931/JD9930 regulator which provides the comparatively high voltages needed for electronic paper displays. Datasheet for the FP9931 is at https://www.fitipower.com/dl/file/flXa6hIchVeu0W3K Although it is in English, it seems to be only downloadable from the Chinese part of that website. For the JD9930 there can be a datasheet found at https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/JD9930_2D00_0.7_2D00_JUN_2D00_2019.pdf To simplify things, include the hwmon part directly which is only one register read and there are not other functions besides regulators in this chip.
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.

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.

2025-11-05regulator: Add support for MediaTek MT6316 SPMI PMIC RegulatorsAngeloGioacchino Del Regno
Add a driver for the regulators found on all types of the MediaTek MT6316 SPMI PMIC, fully controlled by SPMI interface and featuring four step down DCDC (buck) converters. In particular, this includes support for: - MT6316(BP/VP): 2+2 Phase (Phase 1: buck1+2, Phase 2: buck3+4) - MT6316(CP/HP/KP): 3+1 Phase (Phase 1: buck1+2+4, Phase 2: buck3) - MT6316(DP/TP): 4+0 Phase (Single phase, buck1+2+3+4) Please note that the set/clear registers for the enable bits are not documented in the datasheet version that I used as reference, but those are used in the downstream driver and I verified that are actually working as expected. Besides, it's also worth clearly mentioning that the MT6316 PMICs voltage selector register uses a weird 9-bits Big Endian format, for which a driver-private helper is provided.

The driver implements basic voltage control and sending error notifications. NOTE: The driver does not support doing configuration which require the PMIC to be in STBY state. The omitted feature set includes setting safety limit values, changing LDO voltages and controlling enable state for some regulators. Also, the ERRB IRQ is not handled.

2024-06-13regulator: add pm8008 pmic regulator driverJohan Hovold
The Qualcomm PM8008 is an I2C-controlled PMIC containing seven LDO regulators. The driver is based on a driver submitted by Satya Priya, but it has been cleaned up and reworked to match the new devicetree binding which no longer describes each regulator as a separate device. This avoids describing internal details like register offsets in the devicetree and allows for extending the implementation with features like over-current protection without having to update the binding. Specifically note that the regulator interrupts are shared between all regulators. Note that the secondary regmap is looked up by name and that if the driver ever needs to be generalised to support regulators provided by the primary regmap (I2C address) such information could be added to the device-id table. This also fixes the original implementation, which looked up regulators by 'regulator-name' property rather than devicetree node name and which prevented the regulators from being named to match board schematics.

2024-02-22treewide: update LLVM Bugzilla linksNathan Chancellor
LLVM moved their issue tracker from their own Bugzilla instance to GitHub issues. While all of the links are still valid, they may not necessarily show the most up to date information around the issues, as all updates will occur on GitHub, not Bugzilla. Another complication is that the Bugzilla issue number is not always the same as the GitHub issue number. Thankfully, LLVM maintains this mapping through two shortlinks: https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num> https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num> Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the "https://llvm.org/pr<num>" shortlink so that the links show the most up to date information. Each migrated issue links back to the Bugzilla entry, so there should be no loss of fidelity of information here.
