+ - reset-gpios: Should specify the gpio for bluetooth reset + - host-wakeup-gpios: Should specify the gpio for host wakeupShould be interrupt instead?Yes this is mostly an interrupt, but I need to read the current line state.When? If the interrupt is level triggered, then you can get the line state based on whether you get an interrupt or not. If this needs to be a wakeup source (see the wakeup source binding), then it needs to be an interrupt.
What is wrong with GPIO? It is simply a piece of wire. Yes, we'll configure it to generate an interrupt, or maybe not, but that's software detail, the device tree just should not care....
