Thanks for your assistance! What I did just now was to make use of the
'uie_unsupported' flag. This is the outcome:


[==========] Running 7 tests from 2 test cases.

[       OK ] rtc.alarm_wkalm_set_minute
[==========] 5 / 7 tests passed.
[  FAILED  ]

I wonder why the_set_minute tests pass, but the other ones fail. I also
wonder why I need the uie_unsupported flag? It's been a while since I
dug into the RTC subsystem, I may be missing something. But I see the
UIE code finally calling into set_alarm for some codepath. We have that
for DA9063, but it is not executed for the UIE test of rtctest. However,
it seems the driver doesn't support this in an optimal way, because
there is a currently unused update interrupt which should be used for
UIE, or? I also wonder why all this works fine for Steve.

Thanks,
