PCIe probe failure on AmLogic A311D after 6.18-rc1

[Linnaea Lavia]

Hi all,

I'm getting the following in dmesg after installing 6.18-rc1 on a VIM3 board.

[    5.391324] [     T50] dw-pcie fc000000.pcie: error -ENXIO: IRQ index 1 not found
[    5.411265] [     T50] meson-pcie fc000000.pcie: host bridge /soc/pcie at fc000000 ranges:

I think the problem is related to c96992a24bec("PCI: dwc: Add support for ELBI resource mapping")
and 2f2cea1ea70a("PCI: dwc/meson: Rework PCI config and DW port logic register accesses"), as they're
both trying to map ELBI/DBI registers.
