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 Russell's for-armsoc branch plus my
local timer series.

Branch also available at:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git arch_timers-for-rmk

* From the initial revision:
- Fixed global timer registration when an SMP kernel is running on UP
  with LOCAL_TIMERS enabled.

Marc Zyngier (4):
  ARM: local timers: Add A15 architected timer support
  ARM: architected timers: Add A15 specific sched_clock implementation
  ARM: architected timers: add DT support
  ARM: architected timers: add support for UP timer
