[PATCH 00/11] sp804 and integrator timer CLKSRC_OF support

From: Rob Herring <rob.herring at calxeda.com>

This series add device-tree support using CLKSRC_OF for initialization
of integrator ap and cp timers and sp804 timers. The timer code for all
of these is moved to drivers/clocksource. The common DT based
initialization of sp804 is supported on highbank, versatile-ab and
vexpress. The DT init support is newly added for versatile-ab.

This series is dependent on my CLKSRC_OF clean-up in arm-soc, my
sched_clock selection series[1], and Arnd's default machine descriptor
patch (for default clocksource_of_init call). The full series is
available here:

git://sources.calxeda.com/kernel/linux.git arm-timers

http://sources.calxeda.com/gitweb/?p=kernel/linux.git;a=shortlog;h=refs/heads/arm-timers

I've tested integrator and versatile on qemu and on highbank h/w.

  ARM: timer-sp: convert to use CLKSRC_OF init
  ARM: highbank: use OF init for sp804 timer
  ARM: vexpress: remove sp804 OF init
  ARM: dts: vexpress: disable CA9 core tile sp804 timer
  ARM: versatile: add versatile dtbs to dtbs target
  ARM: versatile: use OF init for sp804 timer
