clock, usually rtc0. Initialization is done when the system
starts up, and when it resumes from a low power state.
+ 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).
