Pull timer updates from Thomas Gleixner:
 "Updates for time, timekeeping and timers:

  Core:

   - Avoid superfluous deactivation of the tick in the low resolution
     tick NOHZ interrupt handler as the deactivation is handled already
     in the idle loop and on interrupt exit.

   - Update stale comments in the tick NOHZ code and rename the tick
     handler functions to be self-explanatory.

   - Remove an unused function in the tick NOHZ code, which was
     forgotten when the last user went away.

   - Handle RTC alarms which exceed the maximum alarm time of the
     underlying RTC hardware gracefully.

     Setting RTC alarms which exceed the maximum alarm time of the RTC
     hardware failed so far and caused suspend operations to abort.

     Cure this by limiting the alarm to the maximum alarm time of the
     RTC hardware, which is provided by the driver. This causes early
     resume wakeups, but that's way better than not suspending at all.

  Drivers:

   - Add a proper clocksource/event driver for the ancient Cirrus Logic
     EP93xx SoC family, which is one of the last non device-tree
     holdouts in arch/arm.

   - The usual boring device tree bindings updates and small fixes and
     enhancements all over the place"
