[RFC 0/5] add rtc support

[Antony Pavlov]

This patchseries imports RTC support from linux-3.15.

User can use 'hwclock' command to see realtime clock readout.

Tested with DS1307.

TODOs:

 * rtc_set_time() is not realized;
 * ds1307_set_time() is not tested;
 * bcd lib is compiled in even if rtc support is disabled (as linux does);
   we can make it optional;
 * adjust include/linux/rtc.h and include/rtc.h;
 * rtc_unregister() is not realized.


Antony Pavlov (5):
  lib: import 'bcd' from linux-3.15
  add rtc support
  i2c: import SMBus stuff from linux
  rtc: add ds1307 support
  commands: add hwclock
