Shall I > cc here someone? I'm actually wondering about this ... I somehow remember writing a response, but don't see it in my history - so it might have gotten lost before I actually sent it. I think the biggest issue I have is that none of that is tested on any hardware and looking at other brcm wifi drivers in the kernel, the interrupt polarity seems to be all over the place, some set it high, some low and I even have seen edge triggers. As all changes are in regard to (copied) brcm wifi node, it would be really interesting to actually know what trigger is the right one. I've Cc'ed Jagan who I think has worked on an affected board, maybe he can check which trigger is correct.
