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.
