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.
