mfd: sec: Use chained IRQs for s2mpg10

2025-11-20T10:29:20Z

On S2MPG10 (and similar like S2MPG11), top-level interrupt status and mask registers exist which need to be unmasked to get the PMIC interrupts. This additional status doesn't seem to exist on other PMICs in the S2MP* family, and the S2MPG10 driver is manually dealing with masking and unmasking currently. The correct approach here is to register this hierarchy as chained interrupts, though, without any additional manual steps. Doing so will also simplify addition of other, similar, PMICs (like S2MPG11) in the future. Update the driver to do just that.

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: Add support for S2MPU05 PMIC

2025-03-13T12:38:45Z

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.

rtc: s5m: Drop S5M8763 support

2023-04-26T10:40:26Z

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: Fix RTC alarm interrupt number on S2MPS11

2015-04-09T09:26:54Z

The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of RTC alarms 0 and 1 were inversed between these two devices. So when rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to S2MPS11_IRQ_RTCA1, not RTCA0. Fix this by using consistent RTC alarm interrupt numbers and adding a BUILD_BUG_ON for future generations. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones
