[PATCH] RTC subsystem: class
Add the basic RTC subsystem infrastructure to the kernel. rtc/class.c - registration facilities for RTC drivers rtc/interface.c - kernel/rtc interface functions rtc/hctosys.c - snippet of code that copies hw clock to sw clock at bootup, if configured to do so.

+ probably want to enable one of more of the interfaces below.

+ This driver can also be built as a module. If so, the module
