Tested on da850-lcdk using tools/testing/selftests/timers/rtctest.c:

/ # ./rtctest

                        RTC Driver Test Example.

Counting 5 update (1/sec) interrupts from reading /dev/rtc0: 1 2 3 4 5
Again, from using select(2) on /dev/rtc: 1 2 3 4 5

Current RTC date/time is 1-1-2000, 00:00:25.
Alarm time now set to 00:00:30.
Waiting 5 seconds for alarm... okay. Alarm rang.

Periodic IRQ rate is 1Hz.
Counting 20 interrupts at:
2Hz:     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
4Hz:     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
8Hz:     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
16Hz:    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
32Hz:    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
64Hz:    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
