mfd: sec: Add support for S2MPG11 PMIC via ACPM

2026-02-04T10:37:29+00:00

Add support for Samsung's S2MPG11 PMIC, which 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. Like S2MPG10, communication is not via I2C, but via the Samsung ACPM firmware. While at it, we can also switch to asynchronous probe, which helps with probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in parallel. Note: The firmware uses the ACPM channel ID and the Speedy channel ID to select the PMIC address. Since these are firmware properties, they can not be retrieved from DT, but instead are deducted from the compatible for now.

mfd: sec: Drop now unused struct sec_pmic_dev::irq_data

2026-01-20T15:37:48+00:00

This was used only to allow the s5m RTC driver to deal with the alarm IRQ. That driver now uses a different approach to acquire that IRQ, and ::irq_data doesn't need to be kept around anymore.

mfd: sec: Change device_type to int

2025-05-23T07:48:44+00:00

Now that sec-i2c doesn't match device type by pointer casting anymore, we can switch the device type from unsigned long to int easily. This saves a few bytes in struct sec_pmic_dev due to member alignment.

mfd: sec: Add support for S2MPG10 PMIC

2025-05-23T07:48:27+00:00

Add support for Samsung's S2MPG10 PMIC, which is a Power Management IC for mobile applications with buck converters, various LDOs, power meters, RTC, clock outputs, and additional GPIOs interfaces. Contrary to existing Samsung S2M series PMICs supported, communication is not via I2C, but via the Samsung ACPM firmware. This commit adds the core driver.

mfd: sec: Move private internal API to internal header

2025-05-23T07:48:22+00:00

sec_irq_init() is an internal API for the core driver, and doesn't belong into the public header. Due to an upcoming split of the driver into a core and i2c driver, we'll also be adding more internal APIs, which again shouldn't be in the public header. Move it into a new internal include.

mfd: sec-core: Drop non-existing forward declarations

2025-05-23T07:48:18+00:00

sec_irq_resume() was removed in commit 6445b84abf91 ("mfd: Add s2mps11 irq driver") and sec_irq_exit() in commit 3dc6f4aaafbe ("mfd: sec: Use devm_mfd_add_devices and devm_regmap_add_irq_chip") while the prototypes were left. They should be removed. Do so. Reviewed-by: Krzysztof Kozlowski Signed-off-by: André Draszik Link: https://lore.kernel.org/r/20250409-s2mpg10-v4-4-d66d5f39b6bf@linaro.org Signed-off-by: Lee Jones

mfd: sec: Add support for S2MPU05 PMIC

2025-03-13T12:38:45+00:00

Add support for Samsung's S2MPU05 PMIC. It's the primary PMIC used by Exynos7870 devices. It houses regulators (21 LDOs and 5 BUCKs) and a RTC clock device.

mfd: sec-core: Add support for the Samsung s2dos05

2024-10-16T08:04:10+00:00

S2DOS05 is a panel/touchscreen PMIC, often found in Samsung phones. We define regulator sub-device for which driver will be added in subsequent patch. The device also has ADC for power and current measurements.

rtc: s5m: Drop S5M8763 support

2023-04-26T10:40:26+00:00

The S5M8763 MFD has no device tree compatible, and since board file support for it was removed, there's no way to use this MFD. After removing the remaining code for it from the MFD driver, also remove support for it in the s5m RTC driver, and all remaining references to it.

mfd: sec: Remove PMICs without compatibles

2023-04-26T10:40:26+00:00

The S5M8751 and S5M8763 PMIC chips have no corresponding compatible values, so since board file support was removed for this driver, there is no way to specify these PMICs as present in boards anymore. Remove leftovers of these chips since it's dead code.
