Hi all: The initial DT-base ls2x rtc driver was written by Wang Xuerui, he has released five versions of patchset before, and all related mail records are shown below if you are interested: https://lore.kernel.org/all/?q=ls2x-rtc In this series of patches, based on the code above, I have added the following support: 1. Add ACPI-related support, as Loongson-3 + LS7A is now ACPI-base by default on LoonArch; 2. Add rtc alarm/walarm related functions. Unfortunately, I have only tested the Loongson-3A4000+LS7A1000/LS7A2000 under LoongArch architecture. NOTE: The related functions of rtc alarm/walarm depend on ACPI registers, so rtc alarm may not be available on the DT-base environment. Such as Loongson-2k/3 under MIPS. Thanks.
