rtc: mt6397: select IRQ_DOMAIN instead of depending on it

2024-02-29T21:37:58Z

IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Relying on it being set for a dependency is risky. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on" for IRQ_DOMAIN to "select" for RTC_DRV_MT6397.

rtc: Add driver for Nuvoton ma35d1 rtc controller

2023-12-17T22:43:20Z

The ma35d1 rtc controller provides real-time and calendar messaging capabilities. It supports programmable time tick and alarm match interrupts. The time and calendar messages are expressed in BCD format. This driver supports the built-in rtc controller of the ma35d1. It enables setting and reading the rtc time and configuring and reading the rtc alarm.

rtc: Add support for the SSD202D RTC

2023-10-16T14:54:15Z

Newer SigmaStar SSD202D SoCs contain a Real Time Clock, capable of running while the system is sleeping (battery powered), this is not the case with the other RTC on older SoCs. This adds basic support for this RTC block.

rtc: bq4802: add sparc dependency

2023-07-27T21:09:55Z

The added HAS_IOPORT dependency might not actually be necessary as Geert points out, but the driver is also only used on one architecture. Sparc is also a special case here since it converts port numbers into virtual addresses rather than having them mapped into a particular part of the __iomem address space, so the difference is actually not important here. Add a dependency on sparc, but allow compile-testing otherwise, to make this clearer without anyone having to spend much time modernizing the driver beyond that.

rtc: pcf2127: add support for PCF2131 RTC

2023-07-27T20:54:52Z

This RTC is very similar in functionality to the PCF2127/29. Basically it: -supports two new control registers at offsets 4 and 5 -supports a new reset register (not implemented in this driver) -supports 4 tamper detection functions instead of 1 -has no nvmem (like the PCF2129) -has two output interrupt pins Because of that, most of the register addresses are very different, although they still follow the same layout. For example, the tamper registers have a different base address, but the offsets are all the same.
