Disabling the driver leads to a booting system again. Booting
with DT seems OK.
I can see two issues here: we have a screaming interrupt, and
we seem to corrupt some workqueue.
How did you get this to work? Firmware release?
Thanks,
M.

FWIW, mainline booting with this patch on Juno r1 with ACPI enabled
dies a horrible death:

Disabling the driver leads to a booting system again. Booting

How did you get this to work? Firmware release?
Thanks,
