rtc: mt6397: select IRQ_DOMAIN instead of depending on it

2024-03-26T22:20:06+00:00

[ Upstream commit 544c42f798e1651dcb04fb0395219bf0f1c2607e ] 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: bq4802: add sparc dependency

2023-07-27T21:09:55+00:00

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

2023-07-27T20:54:52+00:00

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.

The Loongson family chips use an on-chip counter 0 (Time Of Year counter) as the RTC. We will refer to them as rtc-loongson.
