regulator: dt-bindings: qcom,qca6390-pmu: Document WCN6755 PMU

2026-04-06T13:16:40Z

Document the WCN6755 PMU using a fallback to WCN6750 since the two chips seem to be completely pin and software compatible. In fact the original downstream kernel just pretends the WCN6755 is a WCN6750.

regulator: dt-bindings: regulator-max77620: convert to DT schema

2026-04-06T13:09:20Z

Convert regulator-max77620 devicetree bindings for the MAX77620 PMIC from TXT to YAML format. This patch does not change any functionality; the bindings remain the same.

regulator: mt6315: add regulator supplies

2026-03-30T14:45:39Z

Chen-Yu Tsai says: This series is part of a broader collection of regulator related cleanups for MediaTek Chromebooks. This one covers the MT6315 PMIC. Patch 1 adds the names of the power supply inputs to the binding. Patch 2 adds the supply names from the DT binding change in patch 1 to the regulator descriptions in the driver. This patch has a checkpatch.pl warnings, but I wonder if it's because the context size for checking complex macros is not large enough. Device tree changes will be sent separately. The goal is to get the regulator tree as complete as possible. This includes adding supply names to other regulator DT bindings, and adding all the supply links to the existing DTs.

2026-03-30T14:45:36Z

The MT6315 family of PMICs has 4 buck regulators. Each regulator has a separate supply. Add these supplies to the device tree binding. Signed-off-by: Chen-Yu Tsai Link: https://patch.msgid.link/20260326081050.1115201-2-wenst@chromium.org Signed-off-by: Mark Brown

regulator: da91xx: Allow caching of buck registers when no GPIO input control is configured

2026-03-24T19:37:47Z

André Svensson 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.

regulator: dt-bindings: dlg,da9121: Add dlg,no-gpio-control

2026-03-24T19:37:44Z

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.

regulator: cros-ec: cleanup and add supplies

Chen-Yu Tsai says: This series is part of a broader collection of regulator related cleanups for MediaTek Chromebooks. This one covers the regulators exposed by the ChromeOS Embedded Controller.

regulator: fp9931: Make vin-supply mandatory

2026-03-17T18:07:38Z

Robby Cai says: The FP9931 regulator requires a valid "vin" supply to operate correctly. Therefore, the driver should treat "vin" as a mandatory supply. This patchset updates the binding documentation to mark vin-supply as a required property, and modifies the driver accordingly. As suggested in the reviews from Andreas and Mark, v2 switches to using devm_regulator_get() since the supply is mandatory.
