Merge tag 'timers-clocksource-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip

Pull clocksource updates from Thomas Gleixner:
 "Updates for clocksource/clockevent drivers:

   - Add devm helpers for clocksources, which allows to simplify driver
     teardown and probe failure handling.

   - More module conversion work

   - Update the support for the ARM EL2 virtual timer including the
     required ACPI changes.

   - Add clockevent and clocksource support for the TI Dual Mode Timer

   - Fix the support for multiple watchdog instances in the TEGRA186
     driver

   - Add D1 timer support to the SUN5I driver

   - The usual devicetree updates, cleanups and small fixes all over the
     place"
