Hi Lorenzo,
As our previous discussion, I make a patchset showing the required
effort if we want to use ->private in pci_host_bridge to store ACPI
device pointer on ARM64. This patchset is mostly for discussion purpose.
This patchset is based onto the v5 of my Hyper-V PCI on ARM64 patchset:
https://lore.kernel.org/lkml/20210726180657.142727-1-boqun.feng@gmail.com/
, and I've tested it with other code under development to fully enable
Hyper-V virtual PCI on ARM64.
Regards,
Boqun

bridges
PCI: hv: Remove the dependency of pci_config_window
