Several devices integrated into LS7A report 1 (which means they use INTA) in their Interrupt Pin registers, but they actually use a different interrupt. Add a quirk to override the incorrect Interrupt Pin values. This is only needed by ACPI-based systems. For DT-based systems, pci_assign_irq() ignores the Interrupt Pin register except to learn that the device uses INTx and the host bridge .map_irq() function (loongson_map_irq()) learns the IRQ mapping via DT and of_irq_parse_pci(). [bhelgaas: drop PCIE_PORT_x, OHCI, GPU since they are function 0 and don't need the quirk, squash in updates from https://lore.kernel.org/r/CAAhV-H40_o+9KS1t67O98GusM38pDaiB4bssxd3KQZpAByfnLg@mail.gmail.com] Link: https://lore.kernel.org/r/20220714124216.1489304-8-chenhuacai@loongson.cn Signed-off-by: Jianmin Lv <lvjianmin@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |
