tests: kernel: tickless: tickless_concept: Support more frequencies (5cbae7f2) · Commits · Wenxi XU / zephyr

Test was assuming that CONFIG_SYS_CLOCK_TICKS_PER_SEC=100 but such frequency is not well supported on SoC which are based on 32768 Hz RTC clock. Align test to be able to work with different sys_clock frequency by converting previously 20 ticks to milliseconds. Set CONFIG_SYS_CLOCK_TICKS_PER_SEC=32768 when system clock is using Nordic RTC timer driver. Signed-off-by:
