In the cover letter, please be explicit about any dependencies that are
not upstream.  This series applies to mainline (v4.7-rc*) but does not
build.  I tested it with my v4.7/integ branch and it seems to work.

The series also has a handful of checkpatch warnings that should be
addressed (see: http://hastebin.com/tacurokasu.pas)

Other than that, I gave it a quick spin on meson8b-odroidc1 using
tools/testing/selftests/timers/rtctest.c, and the basic time stuff seems
to be working:

/ # ./rtctest
