This happened to work, but the code merged in turned out to be far from perfect, and had several flaws. This patchset hopefully fixes these flaws, and cleanup most of the driver as well, to end up in an almost complete rewrite of it (even though it's not that long). It also finally adds a clocksource from the free running counter found in the A10/A13 SoCs. These flaws have all been spotted when trying to add the A31 support, work that is still ongoing, but will hopefully benefit from this patchset as well. Thanks, Maxime Changes from v1: - Rebased on top of linux-next to benefit from the move to all architectures of the sched_clock functions - Moved the clock source to the second timer instead of the 64 bits free-running counter like suggested by Thomas.
