Merge tag 'timers-core-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner:
 "The time and timers updates contain:

  Core changes:

   - Allow runtime power management when the clocksource is changed.

   - A correctness fix for clock_adjtime32() so that the return value on
     success is not overwritten by the result of the copy to user.

   - Allow late installment of broadcast clockevent devices which was
     broken because nothing switched them over to oneshot mode. This
     went unnoticed so far because clockevent devices used to be built
     in, but now people started to make them modular.

   - Debugfs related simplifications

   - Small cleanups and improvements here and there

  Driver changes:

   - The usual set of device tree binding updates for a wide range of
     drivers/devices.

   - The usual updates and improvements for drivers all over the place
     but nothing outstanding.

   - No new clocksource/event drivers. They'll come back next time"
