Pull timer updates from Thomas Gleixner:
 "A rather small set of patches from the timer departement:

   - Some more y2038 work
   - Yet another new clocksource driver
   - The usual set of small fixes, cleanups and enhancements"

* 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  clocksource/drivers/tegra: Remove unused suspend/resume code
  clockevents/driversi/mps2: add MPS2 Timer driver
  dt-bindings: document the MPS2 timer bindings
  clocksource/drivers/mtk_timer: Add __init attribute
  clockevents/drivers/dw_apb_timer: Implement ->set_state_oneshot_stopped()
  time: Introduce do_sys_settimeofday64()
  security: Introduce security_settime64()
  clocksource: Add missing include of of.h.
