Yoshihiro, can you fix this by adding structs for the of_device_id.data member instead of casting DW_PCIE_RC_TYPE and DW_PCIE_EP_TYPE? Examples here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pci-dra7xx.c?id=v6.6#n557 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pci-keystone.c?id=v6.6#n1069 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pcie-artpec6.c?id=v6.6#n452 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pcie-designware-plat.c?id=v6.6#n159 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pcie-keembay.c?id=v6.6#n437 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pcie-tegra194.c?id=v6.6#n2431 Siddharth, since you're looking at keystone v3.65, it looks to me like DW_PCIE_VER_365A is currently broken because ks_pcie_rc_of_data doesn't set .mode, so it defaults to zero, and it looks like we should end up at the INVALID device type case here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/dwc/pci-keystone.c?id=v6.6#n1285 > |-- arm64-buildonly-randconfig-r003-20220511 > | `-- aarch64-linux-ld:drivers-cxl-core-pci.c:(.text):undefined-reference-to-pci_print_aer > |-- csky-randconfig-001-20231030 > | |-- csky-linux-ld:pci.c:(.text):undefined-reference-to-pci_print_aer > | `-- pci.c:(.text):undefined-reference-to-pci_print_aer > |-- i386-randconfig-141-20231030 > | |-- ld:drivers-cxl-core-pci.c:undefined-reference-to-pci_print_aer > |-- loongarch-randconfig-r014-20230225 > | `-- drivers-cxl-core-pci.c:(.text):undefined-reference-to-pci_print_aer > |-- loongarch-randconfig-r032-20220926 > | `-- loongarch64-linux-ld:drivers-cxl-core-pci.c:(.text):undefined-reference-to-pci_print_aer > |-- powerpc-randconfig-003-20231016 > | `-- powerpc-linux-ld:pci.c:(.text):undefined-reference-to-pci_print_aer > |-- riscv-randconfig-r002-20220124 > | `-- arch-riscv-include-asm-mmio.h:(.text):undefined-reference-to-pci_print_aer > |-- riscv-randconfig-r011-20220606 > | `-- riscv64-linux-ld:pci.c:(.text):undefined-reference-to-pci_print_aer > |-- x86_64-randconfig-x052-20230810 > | `-- drivers-cxl-core-pci.c:undefined-reference-to-pci_print_aer
