This driver handles the RTC of most davinci SoCs. Cc: Sekhar Nori <redacted> Cc: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Karl Beldan <redacted>

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
