Merge tag 'swarren-for-3.9-arm-timer-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup

From Stephen Warren:
ARM/...: timer and clock events cleanup, and remove struct sys_timer

This branch contains a number of cleanups and unifications to various
timer- clock-events- and ARM timer code. The main points are:

1) Convert arch_gettimeoffset to a pointer, so that architectures with
   multiple timer implementations can simply set this standard pointer
   rather than maintaining their own arch-specific pointers for the
   same purpose. Various architectures are converted to using this new
   feature.

2) Conversion of ARM timer implementations to use clock_event_devices's
   suspend/resume operations, rather than the ARM-specific sys_timer
   versions. Thus, the ARM code begins to use more common infra-structure
   rather than arch-specific code.

3) Removal of ARM's struct sys_timer completely, now that everything uses
   common code.

4) Introduction of drivers/clocksource/clksrc-of.c, which allows ARM clock
   source implementations to be moved into drivers/clocksource, with the
   need to add SoC-specific header files for each timer initialization
   function; instead, all enabled implementations are registered into a
   table which a single core function iterates over, and calls the
   relevant initialization functions based on device tree. At least the
   Tegra and BCM2835 clocksource implementations will use this feature in
   the 3.9 kernel cycle.
