Hi Thomas,

This looks really useful, and it's going to conflict with my arch_timer /
arm_generic driver unification series [1].

I'm happy to take this as part of my series if that's ok with you?

Sure, that's fine. This patch would probably be needed in 3.9 on
Exynos platforms. So you could squash this change into your series.

Thanks,
Thomas.

Add an entry in __clksrc_of_table so that ARMv7 architected timer is
discoverable using call to clocksource_of_init.
