Pull RTC updates from Alexandre Belloni:
 "This includes new ioctls to get and set parameters and in particular
  the backup switch mode that is needed for some RTCs to actually enable
  the backup voltage (and have a useful RTC).

  The same interface can also be used to get the actual features
  supported by the RTC so userspace has a better way than trying and
  failing.

  Summary:

  Subsystem:
   - Add new ioctl to get and set extra RTC parameters, this includes
     backup switch mode
   - Expose available features to userspace, in particular, when alarmas
     have a resolution of one minute instead of a second.
   - Let the core handle those alarms with a minute resolution

  New driver:
   - MSTAR MSC313 RTC

  Drivers:
   - Add SPI ID table where necessary
   - Add BSM support for rv3028, rv3032 and pcf8523
   - s3c: set RTC range
   - rx8025: set range, implement .set_offset and .read_offset"
