in clockevents/clockevents/next breaks the boot on e.g. r8a7791/koelsch
(arm32) and r8a7795/salvator-x (arm64).

Using "earlycon keep_bootcon" on koelsch (this doesn't help on arm64)
reveals it's stuck at:

clocksource_probe: no matching clocksources found
sched_clock: 32 bits at 100 Hz, resolution 10000000ns, wraps every
21474836475000000ns
Calibrating delay loop...

With the above commit reverted, it works again:

Architected cp15 timer(s) running at 10.00MHz (virt).
clocksource: arch_sys_counter: mask: 0xffffffffffffff max_cycles:
0x24e6a1710, max_idle_ns: 440795202120 ns
sched_clock: 56 bits at 10MHz, resolution 100ns, wraps every
4398046511100ns
Switching to timer-based delay loop, resolution 100ns
Calibrating delay loop (skipped), value calculated using timer
frequency.. 20.00 BogoMIPS (lpj=100000)

I think it is fixed now and pushed on my tree. Is it possible to confirm
your boards are working correctly again after the linux-next is updated with
my latest changes ?

I can confirm the issue is fixed in today's clockevents/next
(52be039599e1339e).

Great ! Thanks for testing.
