Hmm OK.

Care to try setting the wlcore interrupt in the dts to
IRQ_TYPE_LEVEL_HIGH and see if that helps?

Also please check the interrupt line related pinctrl pull
settings, if there's an external pull resistor the internal
pull should be disabled for the interrupt line.

Hmm maybe give a try for the wlcore ELP wakeup patches I just posted as:

PATCHv2 0/4] Improvments for wlcore irq and resume for v5.9

To me it seems that I'm not seeing any more wlcore firmware reboots
that I was occasionally seeing earlier. Not sure about that though,
I guess we have to wait and see.
