regulator: pca9450: Add support for setting debounce settings

2025-11-18T18:55:22+00:00

Make the different debounce timers configurable from the devicetree. Depending on the board design, these have to be set different than the default register values.

Add support MT6316/6363/MT6373 PMICs regulators

2025-11-06T11:34:53+00:00

Merge series from AngeloGioacchino Del Regno : 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.

regulator: Add support for MediaTek MT6363 SPMI PMIC Regulators

2025-11-05T13:28:46+00:00

Add a driver for the regulators found on the MT6363 PMIC, fully controlled by SPMI interface. This PMIC regulates voltage with an input range of 2.6-5.0V, and features 10 buck converters and 26 LDOs.

regulator: core: forward undervoltage events downstream by default

2025-10-15T09:48:58+00:00

Forward critical supply events downstream so consumers can react in time. An under-voltage event on an upstream rail may otherwise never reach end devices (e.g. eMMC). Register a notifier on a regulator's supply when the supply is resolved, and forward only REGULATOR_EVENT_UNDER_VOLTAGE to the consumer's notifier chain. Event handling is deferred to process context via a workqueue; the consumer rdev is lifetime-pinned and the rdev lock is held while calling the notifier chain. The notifier is unregistered on regulator teardown. No DT/UAPI changes. Behavior applies to all regulators with a supply.

regulator: pca9450: Add restart handler

2025-05-12T12:09:50+00:00

When restarting a CPU powered by the PCA9450 power management IC, it is beneficial to use the PCA9450 to power cycle the CPU and all its connected peripherals to start up in a known state. The PCA9450 features a cold start procedure initiated by an I2C command. Add a restart handler so that the PCA9450 is used to restart the CPU. The restart handler sends command 0x14 to the SW_RST register, initiating a cold reset (Power recycle all regulators except LDO1, LDO2 and CLK_32K_OUT) As the PCA9450 is a PMIC specific for the i.MX8M family CPU, the restart handler priority is set just slightly higher than imx2_wdt and the PSCI restart handler. This makes sure this restart handler takes precedence.

regulator: Add (devm_)of_regulator_get()

2025-02-24T15:26:08+00:00

The Rockchip power-domain controller also plans to make use of per-domain regulators similar to the MediaTek power-domain controller. Since existing DTs are missing the regulator information, the kernel should fallback to the automatically created dummy regulator if necessary. Thus the version without the _optional suffix is needed. The Rockchip driver plans to use the managed version, but to be consistent with existing code the unmanaged version is added at the same time.
