[PATCH v12 00/13] PCI: Use device bus range info to cleanup RC Host/EP pci_fixup_addr()

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

This is a v12 based on Frank's v11 series.

v11 https://lore.kernel.org/r/20250313-pci_fixup_addr-v11-0-01d2313502ab@xxxxxxx
    
Changes from v11:
  - Call devm_pci_alloc_host_bridge() early in dw_pcie_host_init(), before
    any devicetree-related code
  - Call devm_pci_epc_create() early in dw_pcie_ep_init(), before any
    devicetree-related code
  - Consolidate devicetree-related code in dw_pcie_host_get_resources() and
    dw_pcie_ep_get_resources()
  - Integrate dw_pcie_cfg0_setup() into dw_pcie_host_get_resources()
  - Convert dw_pcie_init_parent_bus_offset() to dw_pcie_parent_bus_offset()
    which returns the offset rather than setting it internally
  - Split the debug comparison of devicetree info with .cpu_addr_fixup() to
    separate patch so we can easily revert it later
  - Drop "cpu_addr_fixup() usage detected" warning since we always warn
    about something in that case anyway

Any comments welcome.


Bjorn Helgaas (3):
  PCI: dwc: Consolidate devicetree handling in
    dw_pcie_host_get_resources()
  PCI: dwc: ep: Call epc_create() early in dw_pcie_ep_init()
  PCI: dwc: ep: Consolidate devicetree handling in
    dw_pcie_ep_get_resources()

Frank Li (10):
  PCI: dwc: Use resource start as iomap() input in
    dw_pcie_pme_turn_off()
  PCI: dwc: Rename cpu_addr to parent_bus_addr for ATU configuration
  PCI: dwc: Call devm_pci_alloc_host_bridge() early in
    dw_pcie_host_init()
  PCI: dwc: Add dw_pcie_parent_bus_offset()
  PCI: dwc: Add dw_pcie_parent_bus_offset() checking and debug
  PCI: dwc: Use devicetree 'reg[config]' to derive CPU -> ATU addr
    offset
  PCI: dwc: ep: Use devicetree 'reg[addr_space]' to derive CPU -> ATU
    addr offset
  PCI: dwc: ep: Ensure proper iteration over outbound map windows
  PCI: dwc: Use parent_bus_offset to remove need for .cpu_addr_fixup()
  PCI: imx6: Remove cpu_addr_fixup()
