That would be required if we implement an interrupt controller or UART driver which need to know if it's a rising/falling edge or low/high level interrupt. Although I don't see any UART in Linux using the IRQ type. So it would only be an interrupt controller. I guess we could go on this way (i.e only keeping track of level/edge) for now. I will give a look after my device passthrough series.
