Anyway, no big deal. I am not sure about the other non-ilitek devices, but the fruitboards do use at least goodix and etm/edt touch controllers without interrupt line too, those I have on my desk (those two have separate, more extensive, binding document). I also suspect we will see more of those touch controllers with optional interrupt line, so if we do, I think we can re-combine the binding documents again ?
