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.

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.

rtc: Rename lib_test to test_rtc_lib

2025-07-22T10:56:58+00:00

When compiling the RTC library functions test as a module, the module has the non-descriptive name "lib_test.ko". Fix this by renaming it to "test_rtc_lib.ko".

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.

2025-03-17T21:55:37+00:00

The pcf50633 was used as part of the OpenMoko devices but the support for its main chip was recently removed in: commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support") See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/ Remove it.

rtc: support for the Amlogic on-chip RTC

2024-11-12T14:05:31+00:00

This is the third amlogic driver. The RTC hardware of A4 SoC is different from the previous one. This RTC hardware includes a timing function and an alarm function. But the existing has only timing function, alarm function is using the system clock to implement a virtual alarm. Add the RTC driver to support it.

rtc: add driver for Marvell 88PM886 PMIC RTC

2024-11-11T22:37:50+00:00

RTC lives on the chip's base register page. Add the relevant register definitions and implement a basic set/read time functionality. Tested with the samsung,coreprimevelte smartphone which contains this PMIC and whose vendor kernel tree has also served as the sole reference for this.
