To communicate with the DA9063 RTC I am use ioctl function calls

 - RTC_SET_TIME
 - RTC_RD_TIME
 - RTC_ALM_SET
 - RTC_ALM_READ
 - RTC_AIE_ON
 - RTC_AIE_OFF

- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/rtc.txt
- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/rtc

Although I don't use the test programs found in Linux, the ioctl calls I
make are shown in the Linux selftests. I believe that Alexandre Belloni
updated the RTC tests recently -- but I am not up to date with the latest.
