Linus Torvalds a4ae54f90e 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
