For example, along the lines of: dwc3_setup_port_irq(int index) { if (index == 0) try non-mp name else generate mp name lookup and request hs irqs lookup and request ss irq lookup and request power irq } dwc3_setup_irq() { determine if MP (num_ports) for each port dwc3_setup_port_irq(port index) } The port irq helper can either be told using a second argument that this is a non-mp controller, or you can first try looking up one of the non-mp names. My mailer discarded your second patch, but you cannot assume that the devices connected to each port are of the same type (e.g. HS or SS) based on what is connected to the first port. Johan
