Thanks for the patch Steffen, but I have already submitted a patch to fix this.

The patch is in linux-next and staged for an rc in v5.9.

Since commit 6d2e16a3181b ("clocksource: dw_apb_timer_of: Fix missing clockevent timers") the dw_apb_timer_of code tries to add a clockevent for timer3. This reveals the wrong register offset that is provided in the timer3-node in the socfpga_arria10 devicetree which in turn results in

Unhandled fault: imprecise external abort (0x406) at 0xbea9fe20

and therefore in a kernel panic.

Set the offset to the correct value.
