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.
