Here is v2 of the patchset for the ACPI PCI controller driver based on the earlier discussion[1]. This patchset unifies the pci-host-generic ECAM code and the ACPI PCI ECAM code much further so that both the implementations can use the same structure (struct pci_config_window) as ->sysdata. The patchset should also make it easier to share platform quirks between DT and ACPI PCI controller drivers using struct pci_generic_ecam_ops. Short description of the patches in the patchset: - fixup arm64 PCI code so that it can use the generic ACPI PCI driver. - implement pci/drivers/ecam.[ch] which will replace drivers/pci/host/pci-host-common.h API for ECAM access and will be shared by ACPI and DT. - Update users of the pci-host-common API to the ecam API - implement a simple PCI ACPI host. I have not used the pci_mmcfg_list or the region definitions from x86, but have used a much simpler approach here. This should apply cleanly on top of the current 4.6 tree or the pci next tree, and can be reviewed as a patchset. The full set of changes for arm64 includes other fixes, that series is available at https://github.com/jchandra-brcm/linux branch arm64-acpi-pci-v2 This has been tested on qemu with OVMF for the ACPI part and with device tree for pci-host-generic code. Further testing and reviews are welcome. Thanks, JC.
