+Subject: [PATCH 1/2] PCI: iproc: Allow override of device tree IRQ mapping
+ function
+
+The iProc core PCIe driver defaults to using of_irq_parse_and_map_pci() for
+IRQ mapping.  Add iproc_pcie.map_irq so bus interfaces that don't use
+device tree can override this by supplying their own IRQ mapping function.
