help
Generic RTC class support. If you say yes here, you will
be allowed to plug one or more RTCs to your system. You will
probably want to enable one of more of the interfaces below.
This driver can also be built as a module. If so, the module
will be called rtc-class.
config RTC_HCTOSYS
bool "Set system time from RTC on startup"
depends on RTC_CLASS = y
default y
help
If you say yes here, the system time will be set using
the value read from the specified RTC device. This is useful
in order to avoid unnecessary fschk runs.
config RTC_HCTOSYS_DEVICE
string "The RTC to read the time from"
depends on RTC_HCTOSYS = y
default "rtc0"
help
The RTC device that will be used as the source for
the system time, usually rtc0.

[PATCH] RTC subsystem: sysfs interface This patch adds the sysfs interface to the RTC subsystem. Each RTC client will have his own entry under /sys/classs/rtc/rtcN . Within this entry some attributes are exported by the subsystem, like date and time.

help
Say yes here if you want to use your RTC using the sysfs
interface, /sys/class/rtc/rtcX .
This driver can also be built as a module. If so, the module
will be called rtc-sysfs.
[PATCH] RTC subsystem: proc interface Add the proc interface to the RTC subsystem. The first RTC driver which registers with the class will be accessible by /proc/driver/rtc . This is required for compatibility with the standard RTC driver and to avoid breaking any user space application which may erroneusly rely on this.

[PATCH] RTC subsystem: dev interface Add the dev interface to the RTC subsystem. Each RTC will be available under /dev/rtcX .
