Merge tag 'timers-v5.9-rc4' of https://git.linaro.org/people/daniel.lezcano/linux into timers/urgent

Pull clocksource/clockevent fixes from Daniel Lezcano:

 - Fix wrong signed return value when checking of_iomap in the probe
   function for the h8300 timer (Tianjia Zhang)

 - Fix reset sequence when setting up the timer on the dm_timer (Tony
   Lindgren)

 - Fix counter reload when the interrupt fires on gx6605s (Guo Ren)
