c89ac918 - rtc: support for the Amlogic on-chip RTC

Tue, 12 Nov 2024 03:10:15 +0000

rtc: support for the Amlogic on-chip RTCThis is the third amlogic driver. The RTC hardware of A4 SoC is differentfrom the previous one. This RTC hardware includes a timing function andan alarm function. But the existing has only timing function, alarmfunction is using the system clock to implement a virtual alarm. Addthe RTC driver to support it.Signed-off-by: Yiting Deng Signed-off-by: Xianwei Zhao Link: https://lore.kernel.org/r/20241112-rtc-v6-2-a71b60d2f354@amlogic.comSigned-off-by: Alexandre Belloni List of files: /linux-6.15/drivers/rtc/Kconfig

rtc: stm32: add Low Speed Clock Output (LSCO) supportRTC is able to output on a pin the "LSE" internal clock.STM32 RTC is now registered as a clock provider.It provides rtc_lsco clock, that means RTC_LSCO is output on eitherRTC_OUT1 or RTC_OUT2_RMP, depending on pinmux DT property.The clock is marked as CLK_IGNORE_UNUSED and CLK_IS_CRITICAL becauseRTC_LSCO can be early required by devices needed it to init.Add LSCO in pinmux functions.Add "stm32_rtc_clean_outs" to disable LSCO. As RTC is part of "backup"power domain, it is not reset during shutdown or reboot.

544c42f7 - rtc: mt6397: select IRQ_DOMAIN instead of depending on it

Tue, 13 Feb 2024 05:02:58 +0000

rtc: mt6397: select IRQ_DOMAIN instead of depending on itIRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot setit directly thru "make *config", so drivers should select it insteadof 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 reduceKconfig circular dependency issues.Therefore, change the use of "depends on" for IRQ_DOMAIN to"select" for RTC_DRV_MT6397.Fixes: 04d3ba70a3c9 ("rtc: mt6397: add IRQ domain dependency")Cc: Arnd Bergmann Cc: Eddie Huang Cc: Sean Wang Cc: Matthias Brugger Cc: linux-arm-kernel@lists.infradead.orgCc: linux-mediatek@lists.infradead.orgCc: Alessandro Zummo Cc: Alexandre Belloni Cc: linux-rtc@vger.kernel.orgCc: Marc Zyngier Cc: Philipp Zabel Cc: Peter Rosin Reviewed-by: AngeloGioacchino Del Regno Signed-off-by: Randy Dunlap Link: https://lore.kernel.org/r/20240213050258.6167-1-rdunlap@infradead.orgSigned-off-by: Alexandre Belloni List of files: /linux-6.15/drivers/rtc/Kconfig

Wed, 19 Jul 2023 19:28:18 +0000

rtc: bq4802: add sparc dependencyThe added HAS_IOPORT dependency might not actually be necessary as Geertpoints out, but the driver is also only used on one architecture. Sparcis also a special case here since it converts port numbers into virtualaddresses 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, tomake this clearer without anyone having to spend much time modernizingthe driver beyond that.Reported-by: Geert Uytterhoeven Cc: David S.

rtc: pcf2127: add support for PCF2131 RTCThis 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 pinsBecause of that, most of the register addresses are very different,although they still follow the same layout. For example, the tamperregisters have a different base address, but the offsets are all the same.Signed-off-by: Hugo Villeneuve Link: https://lore.kernel.org/r/20230622145800.2442116-12-hugo@hugovil.comSigned-off-by: Alexandre Belloni List of files: /linux-6.15/drivers/rtc/Kconfig
