Merge branch 'timers/core' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer code update from Thomas Gleixner:
- armada SoC clocksource overhaul with a trivial merge conflict
- Minor improvements to various SoC clocksource drivers
* 'timers/core' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
clocksource: armada-370-xp: Add detailed clock requirements in devicetree binding
clocksource: armada-370-xp: Get reference fixed-clock by name
clocksource: armada-370-xp: Replace WARN_ON with BUG_ON
clocksource: armada-370-xp: Fix device-tree binding
clocksource: armada-370-xp: Introduce new compatibles
clocksource: armada-370-xp: Use CLOCKSOURCE_OF_DECLARE
clocksource: armada-370-xp: Simplify TIMER_CTRL register access
clocksource: armada-370-xp: Use BIT()
ARM: timer-sp: Set dynamic irq affinity
ARM: nomadik: add dynamic irq flag to the timer
clocksource: sh_cmt: 32-bit control register support
clocksource: em_sti: Convert to devm_* managed helpers
