device should record time in UTC, since the kernel won't do
timezone correction.
- The driver for this RTC device must be loaded before late_initcall
- functions run, so it must usually be statically linked.
-
This clock should be battery-backed, so that it reads the correct
time when the system boots from a power-off state. Otherwise, your
system will need an external clock source (like an NTP server).
