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.

rtc: support i.MX95 BBM RTC

2024-08-28T20:54:51Z

The BBM module provides RTC feature. To i.MX95, this module is managed by System Manager and exported System Control Management Interface(SCMI). Linux could use i.MX SCMI BBM Extension protocol to use RTC feature. This driver is to use SCMI interface to get/set RTC.
