mfd: sec: Change device_type to int

2025-05-23T07:48:44Z

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

2025-05-23T07:48:27Z

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

2025-05-23T07:48:22Z

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

2025-05-23T07:48:18Z

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: bcm590xx: Drop unused "id" member of bcm590xx struct

2025-05-23T07:48:08Z

The "id" member of the bcm590xx struct is unused and will be confusing once we add an actual PMU ID storage value. Drop it; a replacement will be introduced in a future commit.

mfd: aat2870: Use per-client debugfs directory

2025-05-22T14:49:58Z

The I2C core now provides a debugfs entry for each client. Let this driver use it instead of the custom directory in debugfs root. Further improvements by this change: automatic clean up on removal, support of multiple instances.

regulator: bcm590xx: Store regulator descriptions in table

2025-05-22T09:57:26Z

Instead of filling in the regulator description programatically, store the data in a struct. This will make it a bit nicer to introduce support for other BCM590xx chips besides the BCM59056. To do this, add a new struct type, bcm590xx_reg_data, to store all of the necessary information. Drop the old IS_LDO, IS_GPLDO... macros in favor of the "type" field in this struct. Adapt the old bcm590xx_reg struct to the new types.
