+ string "RTC used to set the system time"

+ help
+ The RTC device that will be used to (re)initialize the system
+ clock, usually rtc0. Initialization is done when the system
+ starts up, and when it resumes from a low power state. This
+ 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).
+
+ If the clock you specify here is not battery backed, it may still
