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.

The DS1307 driver suffered from a bug where it was enabling the

century bit inconditionnally but never used it when reading the time.

It made the driver unable to support dates beyond 2099.

Setting this option will add proper support for the century bit but if

the time was previously set using a kernel predating this option,

reading the date will return a date in the next century.

To solve that, you could boot a kernel without this option set, set

the RTC date and then boot a kernel with this option set.

this driver, otherwise it won't be accessible. This means
