Merge tag 'clksrc-cleanup-for-3.10-part2' of git:// into late/clksrc
This is the 2nd part of ARM timer clean-ups for 3.10. This series has the following changes: - Add sched_clock selection logic to select the highest frequency clock - Use full 64-bit arch timer counter for sched_clock - Convert arch timer, sp804 and integrator-cp timers to CLKSRC_OF and adapt all users to use clocksource_of_init * tag 'clksrc-cleanup-for-3.10-part2' of git:// devtree: add binding documentation for sp804 ARM: integrator-cp: convert use CLKSRC_OF for timer init ARM: versatile: use OF init for sp804 timer ARM: versatile: add versatile dtbs to dtbs target ARM: vexpress: remove extra timer-sp control register clearing ARM: dts: vexpress: disable CA9 core tile sp804 timer ARM: vexpress: remove sp804 OF init ARM: highbank: use OF init for sp804 timer ARM: timer-sp: convert to use CLKSRC_OF init OF: add empty of_device_is_available for !OF ARM: convert arm/arm64 arch timer to use CLKSRC_OF init ARM: make machine_desc->init_time default to clocksource_of_init ARM: arch_timer: use full 64-bit counter for sched_clock ARM: make sched_clock just call a function pointer ARM: sched_clock: allow changing to higher frequency counter Signed-off-by: Olof Johansson <> This has a nasty set of conflicts with the exynos MCT code, which was moved in a separate branch, and then fixed up when merged in, but still conflicts a bit here. It should have been sorted out by this merge though.
