The timeout setting for the rtc kselftest is currently 90 seconds. However, two of the tests set alarms, which take one minute to complete each. So the timeout should be at least 120. Set it to 180, so that all tests are able to complete and still have some slack.

This issue was discovered as part of adding the rtc kselftest to run on KernelCI for the rk3399-gru-kevin device, which uses rtc-cros-ec as the RTC driver.
The output log with the current timeout is shown in [1]. As can be seen, the whole test times out before the alarm_wkalm_set_minute test has had a chance to complete:
# # RUN rtc.alarm_wkalm_set_minute ... # # rtctest.c:294:alarm_wkalm_set_minute:Alarm time now set to 11/01/2022 23:03:00. # not ok 1 selftests: rtc: rtctest # TIMEOUT 90 seconds
With the increased timeout, as shown in [2], the alarm_wkalm_set_minute test does complete its run:
# # RUN rtc.alarm_wkalm_set_minute ... # # rtctest.c:294:alarm_wkalm_set_minute:Alarm time now set to 12/01/2022 15:54:00. # # OK rtc.alarm_wkalm_set_minute # ok 7 rtc.alarm_wkalm_set_minute # # FAILED: 6 / 7 tests passed.
The fact that the alarm_alm_set_minute test times out on its own is probably an issue with the rtc-cros-ec driver. Still, since the tests are independent, all of them should be able to run regardless of how long each one takes (so, assuming the worst case scenario).

Hum, I don't get the logic from that, a test takes up to 60 seconds and the timeout is 90s per test so we already have plenty of slack there.

Actually I did re-test locally and it is an issue since the 90s timeout is not per-test, but to the whole rtc test suite. Also it requires running the test through the selftest runner, and since the alarm is set to the next top of the minute, you might get lucky and it might all take less than 90 seconds.
However none of this was clear in my original commit message, so I'll send a v2 with a better explanation.
Thanks, Nícolas
