[PATCH 00/26] OMAP dmtimer prep series

Here are a couple of patches moving things around in dmtimer and system timer
code simplying, rewriting many parts of it, inorder to prep them for moving out
of plat-omap and mach-omap2 to a generic clocksource driver. These patches are
required before the clocksource migration can be done.

Many of these patches have been out for a while now, I'd like to get any
final feedback and have them merged for v3.16.

The series includes all earlier series posted for OMAP1 timers, OMAP2+ timers,
and common platform dmtimer code [1] [2].

Tests have been performed with system timers on AM335x, DRA7 and OMAP4 Panda.

The code delta is slightly more because a bit of redundancy introduced for fall
back cases in mach-omap2/timer.c and a few more checks etc to simply things in
plat-omap/dmtimer.c. Finally once we move things out to drivers/, there will be
a lot of negative delta so this is a small cost for migration.
