[PATCH 0/7] rtc: ls2x: Add support for the Loongson-2K/LS7A RTC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
