On SM8250 TLMM doesn't use PDC interrupt controller for wakeup events.
Instead it handles them on their own (not implemented yet). In addition
setting wakeup-parent property to &pdc will result in parent hwirq being
set to ~0UL, which interact badly with the irqdomains trimming code. So
remove the wakeup-parent property.

Seems like the tubes where slow last week, but the link works now.
Please take a look and let me know if this works better for you.

Thanks,

I will check this patch. However note, that we need to get 5.10 fixed
wrt TLMM irqs. And the mentioned patch probably doesn't stand a chance
of being merged into 5.10-rc, does it?

If the driver is broken in v5.10-rc and my patch fixes the problem we
should make a case for that and I'm sure Linus Walleij will consider
picking it up as a -rc fix.
