Okay, so the driver uses non-exclusive GPIO. Well, this should be really
fixed now. There is no excuse now "cannot work", because I fixed WSA884x
so new DTS using this method should not be allowed. Non-exclusive in
this driver is buggy and works by pure coincidence. You should see clear
warnings and issues during probe, because working device WILL be reset
by the other device.
