There are alarms which have only minute-granularity. The RTC core already has a flag to describe them. Use this flag to skip tests which require the alarm to support seconds. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> --- Tested with a Renesas RZ-N1D board. This RTC obviously has only minute resolution for the alarms. Output now looks like this: # RUN rtc.alarm_alm_set ... # SKIP Skipping test since alarms has only minute granularity. # OK rtc.alarm_alm_set ok 5 rtc.alarm_alm_set # SKIP Skipping test since alarms has only minute granularity. Before it was like this: # RUN rtc.alarm_alm_set ... # rtctest.c:255:alarm_alm_set:Alarm time now set to 09:40:00. # rtctest.c:275:alarm_alm_set:data: 1a0 # rtctest.c:281:alarm_alm_set:Expected new (1489743644) == secs (1489743647) tools/testing/selftests/rtc/rtctest.c | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-)
