[PATCH] RTC subsystem: proc interface

Browse Source 
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.

Say yes here if you want to use your RTC using the proc
interface, /proc/driver/rtc .
This driver can also be built as a module. If so, the module
will be called rtc-proc.
