(Sorry for the more-or-less necroposting) This is the only mention of irq or interrupt in the entire series, which at first led me to believe there was something missing given that there's a "Nobody cared" message appearing when the port first detects something connected to it followed by something about the irq being disabled. Now I read in the text of another patch (adding a TrimUi dts) that this message comes when an interrupt storm is detected, and given that the value in /proc/interrupts goes from zero to 100K in no time, that seems likely to be the case here as well. What is this interrupt supposed to be about, and can it be handled better?
