From 1ee4d93d5037c9247a81431b563b03e436e3f7b6 Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Wed, 28 Jun 2017 15:14:11 -0500 Subject: [PATCH] PCI: xilinx-nwl: Move to struct pci_host_bridge IRQ mapping functions struct pci_host_bridge gained hooks to map/swizzle IRQs, so that the IRQ mapping can be done automatically by PCI core code through the pci_assign_irq() function instead of resorting to arch-specific implementation callbacks to carry out the same task which force PCI host bridge drivers implementation to implement per-arch kludges to carry out a task that is inherently architecture agnostic. Add map/swizzle IRQs hooks to the xilinx-nwl PCI host driver to move the IRQ allocation into core code and stop relying on arch-specific callbacks.
