Due to this, it broke the support\nfor legacy PCI interrupts when using the pci-aardvark driver (used on\nMarvell Armada 3720 platforms).\n\nIn order to fix this, we make sure the ->map_irq and ->swizzle_irq\nfields of pci_host_bridge are properly filled in.\n\nFixes: 769b461fc0c0 (\"arm64: PCI: Drop DT IRQ allocation from pcibios_alloc_irq()\")\nSigned-off-by: Thomas Petazzoni \nCc: # v4.13+\n---\n drivers/pci/host/pci-aardvark.c | 2 ++\n 1 file changed, 2 insertions(+)","diff":"diff --git a/drivers/pci/host/pci-aardvark.c b/drivers/pci/host/pci-aardvark.c\nindex 6d6a2ae35481..f682650bf037 100644\n--- a/drivers/pci/host/pci-aardvark.c\n+++ b/drivers/pci/host/pci-aardvark.c\n@@ -999,6 +999,8 @@ static int advk_pcie_probe(struct platform_device *pdev)\n \tbridge->sysdata = pcie;\n \tbridge->busnr = 0;\n \tbridge->ops = &advk_pcie_ops;\n+\tbridge->map_irq = of_irq_parse_and_map_pci;\n+\tbridge->swizzle_irq = pci_common_swizzle;\n \n \tret = pci_scan_root_bus_bridge(bridge);\n \tif (ret < 0) {\n","prefixes":["7/7"]}
