(Resending this patchset to Daniel since it looks like Daniel is picking up these types of patches.)
This patchset adds support for memory mapped architected timers. We don't have any other global broadcast timer in our system, so we use the mmio timer during low power modes. The first patch is the binding. The next two patches lay some groundwork so that the last patch is simpler. The final patch adds support for mmio timers. Patches are based on a patch from Mark that removes the physical count reading (clocksource: arch_timer: use virtual counter, message id <1364404312-4427-4-git-send-email-mark.rutl...@arm.com>).
