Hey that's cool, works for me for reading and setting date :)
Just noticed one thing, see below.

I tried rtcwake -s 3, but got the following:

rtcwake: cannot open /sys/class/rtc/rtc0/device/power/wakeup:
No such file or directory
rtcwake: /dev/rtc0 not enabled for wakeup events

Then tried adding "wakeup-source" to above but I think the driver
needs something, maybe probably just PM ops?
