MT2712 RTC is a SoC based RTC with different architecture compared to MT7622 RTC. Changes in V3: 1. change struct mt2712_rtc 2. use 100 as year offset 3. change irq handle thread 4. remove useless rtc time check 5. not modify struct rtc_time in set_time/set_alarm functions 6. modify rtc init function 7. add power lost flag for get_time/set_time functions 8. add .alarm_irq_enable callback 9. set rtc->range_min and rtc->range_max to do range checking 10. use fixed driver name Changes in V2: 1. change minimum year from 1968 to 2000 2. fix lock usage 3. stop to calculate useless day of week 4. stop to set default date after init 5. change the prefix of functions 6. use devm_request_threaded_irq() to replace request_threaded_irq() 7. add mt2712 rtc related files into MAINTAINERS Ran Bi (4): bindings: rtc: add bindings for MT2712 RTC rtc: add support for the MediaTek MT2712 RTC arm64: dts: add RTC nodes for MT2712 MAINTAINERS: add MT2712 RTC files .../devicetree/bindings/rtc/rtc-mt2712.txt | 14 + MAINTAINERS | 2 + arch/arm64/boot/dts/mediatek/mt2712e.dtsi | 6 + drivers/rtc/Kconfig | 10 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-mt2712.c | 422 ++++++++++++++++++ 6 files changed, 455 insertions(+) create mode 100644 Documentation/devicetree/bindings/rtc/rtc-mt2712.txt create mode 100644 drivers/rtc/rtc-mt2712.c
