Subject[Patch v4 5/8] ARM64/PCI/ACPI: Introduce struct pci_controller for ACPI
Date
From: Hanjun Guo <hanjun.guo@linaro.org>

ARM64 ACPI based PCI host bridge init needs a arch dependent
struct pci_controller to accommodate common PCI host bridge
code which is introduced later, or it will lead to compile
errors on ARM64.
