Component Type: kbuild config
Description: /dev/rtcN (character devices)
More info: Say yes here if you want to use your RTCs using the /dev interfaces, which "udev" sets up as /dev/rtc0 through /dev/rtcN. You may want to set up a symbolic link so one of these can be accessed as /dev/rtc, which is a name expected by "hwclock" and some other programs. Recent versions of "udev" are known to set up the symlink for you. If unsure, say Y.
