[PATCH] RTC subsystem: sysfs interface

Browse Source 
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.

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.
