[ Upstream commit f034cc1301e7d83d4ec428dd6b8ffb57ca446efb ]
The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value.
However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds.
In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack.
Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run:
./run_kselftest.sh -c rtc
