of_irq_map_pci - Resolve the interrupt for a PCI device : the device whose interrupt is to be resolved : structure of_irq filled by this function

This function resolves the PCI interrupt for a given PCI device. If a device-node exists for a given pci_dev, it will use normal OF tree walking. If not, it will implement standard swizzling and walk up the PCI tree until an device-node is found, at which point it will finish resolving using the OF tree walking.
