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
|
|
be useful to reinitialize system time when resuming from system
|
|
sleep states. Do not specify an RTC here unless it stays powered
|
|
during all this system's supported sleep states.
