Pull RTC updates from Alexandre Belloni: "This cycle, we have a new RTC driver, for the SpacemiT P1. The optee driver gets alarm support. We also get a fix for a race condition that was fairly rare unless while stress testing the alarms. Subsystem: - Fix race when setting alarm - Ensure alarm irq is enabled when UIE is enabled - remove unneeded 'fast_io' parameter in regmap_config New driver: - SpacemiT P1 RTC Drivers: - efi: Remove wakeup functionality - optee: add alarms support - s3c: Drop support for S3C2410 - zynqmp: Restore alarm functionality after kexec transition" * tag 'rtc-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (29 commits) rtc: interface: Ensure alarm irq is enabled when UIE is enabled rtc: tps6586x: Fix initial enable_irq/disable_irq balance rtc: cpcap: Fix initial enable_irq/disable_irq balance rtc: isl12022: Fix initial enable_irq/disable_irq balance rtc: interface: Fix long-standing race when setting alarm rtc: pcf2127: fix watchdog interrupt mask on pcf2131 rtc: zynqmp: Restore alarm functionality after kexec transition rtc: amlogic-a4: Optimize global variables rtc: sd2405al: Add I2C address. rtc: Kconfig: move symbols to proper section rtc: optee: make optee_rtc_pm_ops static rtc: optee: Fix error code in optee_rtc_read_alarm() rtc: optee: fix error code in probe() dt-bindings: rtc: Convert apm,xgene-rtc to DT schema rtc: spacemit: support the SpacemiT P1 RTC rtc: optee: add alarm related rtc ops to optee rtc driver rtc: optee: remove unnecessary memory operations rtc: optee: fix memory leak on driver removal rtc: x1205: Fix Xicor X1205 vendor prefix dt-bindings: rtc: Fix Xicor X1205 vendor prefix ...

rtc: spacemit: support the SpacemiT P1 RTC

2025-09-16T15:38:21+00:00

Add support for the RTC found in the SpacemiT P1 PMIC. Initially only setting and reading the time are supported. The PMIC is implemented as a multi-function device. This RTC is probed based on this driver being named in a MFD cell in the simple MFD I2C driver.

Microcrystal RV8063 is a real-time clock with SPI interface. Its functionality is very similar to the RV8263 rtc. Signed-off-by: Antoni Pokusinski Link: https://lore.kernel.org/r/20250413130755.159373-4-apokusinski01@gmail.com Signed-off-by: Alexandre Belloni

rtc: s32g: add NXP S32G2/S32G3 SoC support

2025-05-25T21:27:56+00:00

Add a RTC driver for NXP S32G2/S32G3 SoCs. RTC tracks clock time during system suspend. It can be a wakeup source for the S32G2/S32G3 SoC based boards. The RTC module from S32G2/S32G3 is not battery-powered and it is not kept alive during system reset.
