Add ACPI-related support, as Loongson-3A5000 + LS7A is now ACPI-base by default under LoongArch architecture; 2. Add rtc alarm/walarm related functions; 3. Merge LS1X rtc and LS2X rtc into a unified rtc-loongson driver. I have tested on Loongson-3A5000LA+LS7A1000/LS7A2000, Loongson-2K1000LA, Loongson-2K0500 and Loongson-2K2000(ACPI/DT). Thanks to everyone for reviewing and testing the code. ------- v5: patch(1/5) - The reason why ls2x can be removed directly is explained in the commit message; - Use fallback compatible; Thanks to all who participated in the fallback compatible discussion. patch(3/5) - Since ls1b and ls1c have different register definitions, we'd better distinguish them with different configurations(ls1b_rtc_config/ls1c_rtc_config); - Due to the use of fallback compatible, the redundant compatible is removed. We can see the full list of supported chips in dt-binding.. v4: https://lore.kernel.org/linux-rtc/cover.1684983279.git.zhoubinbin@loongson.cn/ - Rebase on the top of rtc-next; - Drop defconfig-related patches; patch(1/5) - New patch, Loongson RTC bindings have been rewritten and we have dropped the wildcard (ls2x) in compatible. Thanks to Krzysztof for your comments; patch(2/5) - New patch, drop the ls1x rtc driver; patch(3/5) - Clear RTC_FEATURE_UPDATE_INTERRUPT bit, for the rtc does not support UIE; - Add LS2K2000 support(DT/ACPI); - Merge ls1x support and name the driver rtc-loongson; Thanks to Jiaxun for his comments and Keguang for his assistance in testing. v3: https://lore.kernel.org/linux-rtc/cover.1681370153.git.zhoubinbin@loongson.cn/ patch(2/7): - Check patchset with "checkpatch.pl --strict"; - Drop static inline functions which are used only once, such as ls2x_rtc_regs_to_time; - Remove the suruct ls2x_rtc_regs and regmap_bulk_xxx() is used to read and write rtc registers; - Clear the RTC wakeup interrupt manually; - Enable the RTC in set_time() and check in read_time(); - device_get_match_data() is used to get ls2x_pm_offset, for LS2k1000 has the different value; - Remove some inexact CONFIG_ACPI. v2: 1. Rebased on top of latest loongarch-next; 2. Add interrupt descriptions to the ls2k and ls7a DTS files to avoid errors when the driver gets the IRQ number, Thanks to Qing Zhang for testing; 3. Remove some inexact CONFIG_ACPI. Thanks.
