Merge tag 'timers-core-2022-10-05' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner:
 "A boring time, timekeeping, timers update:

   - No core code changes

   - No new clocksource/event driver

   - Cleanup of the TI DM clocksource/event driver

   - The usual set of device tree binding updates

   - Small improvement, fixes and cleanups all over the place"
