I tested this on a QuartzPro64 dev board, I applied your series top of my tree:
Collabora's rk3588 + some DT patches to add support for the qp64 board.

Here is the output from the commands you told me to try:

bash-5.1# grep rk_timer /sys/bus/clockevents/devices/*/current_device

bash-5.1# grep -B3 -A14 'Device: rk_timer' /proc/timer_list

Tick Device: mode:     1
Broadcast device
Clock Event Device: rk_timer
 max_delta_ns:   178956969070
 min_delta_ns:   1000
 mult:           51539608
 shift:          31
 mode:           3
 next_event:     150944000000 nsecs
 set_next_event: rk_timer_set_next_event
 shutdown:       rk_timer_shutdown
 periodic:       rk_timer_set_periodic
 event_handler:  tick_handle_oneshot_broadcast

 retries:        0

tick_broadcast_mask: ff

bash-5.1# head -1 /proc/interrupts ; grep rk_timer /proc/interrupts;
sleep 10; grep rk_timer /proc/interrupts
           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5
      CPU6       CPU7
 25:        742        210         52         49       2197       1640
      1089       2341     GICv3 321 Level     rk_timer
 25:        754        222         52         49       2252       1727
      1146       2404     GICv3 321 Level     rk_timer

So it looks like this is working.

Thanks for your work.
