This patch series adds support for the architected timers found in
Cortex-A7 and Cortex-A15. It adds local timer support, sched_clock,
global timer and DT support.
Tested on Cortex A15, based on v3.4-rc3. Branch also available at:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git timers-v3.4-rc3
* From v2:
- Allow the generic code to report that local timers cannot be used.
- Plug local timers into the VExpress DT code.
* From the initial revision:
- Fixed global timer registration when an SMP kernel is running on UP
with LOCAL_TIMERS enabled.
