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: imxdi: Soften dependencies for improved compile coverage

The driver compiles fine on x86_64, so soften the dependencies to ARCH_MXC || COMPILE_TEST. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20231002080529.2535610-2-u.kleine-koenig@pengutronix.de Signed-off-by: Alexandre Belloni

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.

rtc: Add rtc driver for the Loongson family chips

2023-06-25T23:19:11Z

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.

rtc: add HAS_IOPORT dependencies

2023-06-06T21:33:25Z

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to add HAS_IOPORT as dependency for those drivers using them.
