There is only one GIC to rul'em all, but there can be multiple RTCs
in a system.

I understand rtc0 is the main RTC.

drivers/rtc/class.c:            of_id = of_alias_get_id(dev->of_node, "rtc");
drivers/rtc/class.c:            of_id =
of_alias_get_id(dev->parent->of_node, "rtc");

Gr{oetje,eeting}s,
