Merge branch 'pci/host-probe-refactor'
- Use pci_host_bridge.windows list directly instead of splicing in a temporary list for cadence, mvebu, host-common (Rob Herring) - Use pci_host_probe() instead of open-coding all the pieces for altera, brcmstb, iproc, mobiveil, rcar, rockchip, tegra, v3, versatile, xgene, xilinx, xilinx-nwl (Rob Herring) - Convert to devm_platform_ioremap_resource_byname() instead of open-coding platform_get_resource_byname() and devm_ioremap_resource() for altera, cadence, mediatek, rockchip, tegra, xgene (Dejin Zheng) - Convert to devm_platform_ioremap_resource() instead of open-coding platform_get_resource() and devm_ioremap_resource() for aardvark, brcmstb, exynos, ftpci100, versatile (Dejin Zheng) - Remove redundant error messages from devm_pci_remap_cfg_resource() callers (Dejin Zheng) - Drop useless PCI_ENABLE_PROC_DOMAINS from versatile driver (Rob Herring) - Default host bridge parent device to the platform device (Rob Herring) - Drop unnecessary zeroing of host bridge fields (Rob Herring) - Use pci_is_root_bus() instead of tracking root bus number separately in aardvark, designware (imx6, keystone, designware-host), mobiveil, xilinx-nwl, xilinx, rockchip, rcar (Rob Herring) - Set host bridge bus number in pci_scan_root_bus_bridge() instead of each driver for aardvark, designware-host, host-common, mediatek, rcar, tegra, v3-semi (Rob Herring) - Use bridge resources instead of parsing DT 'ranges' again for cadence (Rob Herring) - Remove private bus number and range from cadence (Rob Herring) - Use devm_pci_alloc_host_bridge() to simplify rcar (Rob Herring) - Use struct pci_host_bridge.windows list directly rather than a temporary (Rob Herring) - Reduce OF "missing non-prefetchable window" from error to warning message (Rob Herring) - Convert rcar-gen2 from old Arm-specific pci_common_init_dev() to new arch-independent interfaces (Rob Herring) - Move DT resource setup into devm_pci_alloc_host_bridge() (Rob Herring) - Set bridge map_irq and swizzle_irq to default functions; drivers that don't support legacy IRQs (iproc) need to undo this (Rob Herring) * pci/host-probe-refactor: PCI: Set bridge map_irq and swizzle_irq to default functions PCI: Move DT resource setup into devm_pci_alloc_host_bridge() PCI: rcar-gen2: Convert to use modern host bridge probe functions PCI: of: Reduce missing non-prefetchable memory region to a warning PCI: rcar: Use struct pci_host_bridge.windows list directly PCI: rcar: Use devm_pci_alloc_host_bridge() PCI: cadence: Remove private bus number and range storage PCI: cadence: Use bridge resources for outbound window setup PCI: Move setting pci_host_bridge.busnr out of host drivers PCI: rcar: Use pci_is_root_bus() to check if bus is root bus PCI: rockchip: Use pci_is_root_bus() to check if bus is root bus PCI: xilinx: Use pci_is_root_bus() to check if bus is root bus PCI: xilinx-nwl: Use pci_is_root_bus() to check if bus is root bus PCI: mobiveil: Use pci_is_root_bus() to check if bus is root bus PCI: designware: Use pci_is_root_bus() to check if bus is root bus PCI: aardvark: Use pci_is_root_bus() to check if bus is root bus PCI: Drop unnecessary zeroing of bridge fields PCI: Set default bridge parent device PCI: versatile: Drop flag PCI_ENABLE_PROC_DOMAINS PCI: controller: Remove duplicate error message PCI: controller: Convert to devm_platform_ioremap_resource() PCI: controller: Convert to devm_platform_ioremap_resource_byname() PCI: xilinx: Use pci_host_probe() to register host PCI: xilinx-nwl: Use pci_host_probe() to register host PCI: rockchip: Use pci_host_probe() to register host PCI: rcar: Use pci_host_probe() to register host PCI: iproc: Use pci_host_probe() to register host PCI: altera: Use pci_host_probe() to register host PCI: xgene: Use pci_host_probe() to register host PCI: versatile: Use pci_host_probe() to register host PCI: v3: Use pci_host_probe() to register host PCI: tegra: Use pci_host_probe() to register host PCI: mobiveil: Use pci_host_probe() to register host PCI: brcmstb: Use pci_host_probe() to register host PCI: host-common: Use struct pci_host_bridge.windows list directly PCI: mvebu: Use struct pci_host_bridge.windows list directly PCI: cadence: Use struct pci_host_bridge.windows list directly # Conflicts: # drivers/pci/controller/cadence/pcie-cadence-host.c
