rtc: pcf85063: add support for RV8063

2025-07-23T16:52:08Z

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

2025-05-25T21:27:56Z

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.

rtc: amlogic: Do not enable by default during compile testing

2025-05-24T21:33:22Z

Enabling the compile test should not cause automatic enabling of all drivers, but only allow to choose to compile them. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250417074640.81363-1-krzysztof.kozlowski@linaro.org Signed-off-by: Alexandre Belloni

rtc: pcf50633: Remove

2025-03-17T21:55:37Z

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

2024-11-12T14:05:31Z

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

2024-11-11T22:37:50Z

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.

rtc: renesas-rtca3: Add driver for RTCA-3 available on Renesas RZ/G3S SoC

2024-10-31T23:16:17Z

The RTC IP (RTCA-3) available on the Renesas RZ/G3S SoC has calendar count mode and binary count mode (selectable though RCR2.CNTMD) capabilities, alarm capabilities, clock error correction capabilities. It can generate alarm, period, carry interrupts. Add a driver for RTCA-3 IP. The driver implements calendar count mode (as the conversion b/w RTC and system time is simpler, done with bcd2bin(), bin2bcd()), read and set time, read and set alarm, read and set an offset.
