## Summary This PR extends systimer options for nRF52 arch. It is possible to use ARM SysTick either for tickless or non-tickless mode. It is also possible to now use the RTC peripheral for tickless mode. This also re-enables support for WFI/WFE sleep if RTC is used, since this counter continues to run in this mode (in contrast to SysTick). ## Impact nRF52 architecture timing. The default continues to be SysTick in non-tickless mode so it should behave as before. ## Testing I tested systick in both modes and tickless with RTC. I tested that time moves as expected, sleep returns correctly and also verified it continues to work once the RTC clock wraps-around. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
