Enable on-chip RTC support. The on-chip RTC of this SoC is similar to the previous versions of Samsung SoC. So re-use the existing RTC driver with additional changes required for timer counter specific registers. Setting and getting hardware clock has been tested using 'hwclock' and 'date' utilities. Alarm interrupt has been checked with incrementing interrupt count via "cat /proc/interrupts | grep rtc" for 10sec wakeup time via "echo +10 > /sys/class/rtc/rtc0/wakealarm" Devang Tailor (3): dt-bindings: rtc: s3c-rtc: add compatible for exynosautov9 rtc: s3c: support for exynosautov9 on-chip RTC arm64: dts: exynosautov9: add RTC DT node .../devicetree/bindings/rtc/s3c-rtc.yaml | 1 + .../boot/dts/exynos/exynosautov9-sadk.dts | 4 +++ arch/arm64/boot/dts/exynos/exynosautov9.dtsi | 10 +++++++ drivers/rtc/rtc-s3c.c | 26 +++++++++++++++++++ drivers/rtc/rtc-s3c.h | 4 +++ 5 files changed, 45 insertions(+) base-commit: bc6e0ba6c9bafa6241b05524b9829808056ac4ad -- 2.34.1
