This is a series of clean-ups for the Designware PCI driver. The series primarily reworks the config space accessors to use the existing pci_ops struct and removes various private data that's also present in the pci_host_bridge struct. There's also some duplicated common (PCI and DWC) register defines which I converted to use the common defines. This is compile tested only as I don't have any DWC based h/w, so any testing would be helpful. This is an RFC as it will need to be rebased on 5.9-rc1 and my previous clean-up series. Rob Rob Herring (27): PCI: Allow root and child buses to have different pci_ops PCI: dwc: Use DBI accessors instead of own config accessors PCI: dwc: Allow overriding bridge pci_ops PCI: dwc: Add a default pci_ops.map_bus for root port PCI: dwc: al: Use pci_ops for child config space accessors PCI: dwc: keystone: Use pci_ops for config space accessors PCI: dwc: tegra: Use pci_ops for root config space accessors PCI: dwc: meson: Use pci_ops for root config space accessors PCI: dwc: kirin: Use pci_ops for root config space accessors PCI: dwc: exynos: Use pci_ops for root config space accessors PCI: dwc: histb: Use pci_ops for root config space accessors PCI: dwc: Remove dwc specific config accessor ops PCI: dwc: Use generic config accessors PCI: Also call .add_bus() callback for root bus PCI: dwc: keystone: Convert .scan_bus() callback to use add_bus PCI: dwc: Convert to use pci_host_probe() PCI: dwc: Remove root_bus pointer PCI: dwc: Remove storing of PCI resources PCI: dwc: Simplify config space handling PCI: dwc/keystone: Drop duplicated 'num-viewport' PCI: dwc: Check CONFIG_PCI_MSI inside dw_pcie_msi_init() PCI: dwc/imx6: Remove duplicate define PCIE_LINK_WIDTH_SPEED_CONTROL PCI: dwc/meson: Drop unnecessary RC config space initialization PCI: dwc/meson: Rework PCI config and DW port logic register accesses PCI: dwc/qcom: Use common PCI register definitions PCI: dwc: Remove hardcoded PCI_CAP_ID_EXP offset PCI: dwc/tegra: Use common Designware port logic register definitions drivers/pci/controller/dwc/pci-dra7xx.c | 4 +- drivers/pci/controller/dwc/pci-exynos.c | 45 +-- drivers/pci/controller/dwc/pci-imx6.c | 6 +- drivers/pci/controller/dwc/pci-keystone.c | 90 +++-- drivers/pci/controller/dwc/pci-meson.c | 164 +++------ drivers/pci/controller/dwc/pcie-al.c | 70 +--- drivers/pci/controller/dwc/pcie-artpec6.c | 11 +- .../pci/controller/dwc/pcie-designware-host.c | 319 ++++++------------ .../pci/controller/dwc/pcie-designware-plat.c | 4 +- drivers/pci/controller/dwc/pcie-designware.h | 28 +- drivers/pci/controller/dwc/pcie-histb.c | 45 +-- drivers/pci/controller/dwc/pcie-kirin.c | 43 +-- drivers/pci/controller/dwc/pcie-qcom.c | 31 +- drivers/pci/controller/dwc/pcie-spear13xx.c | 4 +- drivers/pci/controller/dwc/pcie-tegra194.c | 90 +++-- drivers/pci/controller/dwc/pcie-uniphier.c | 3 +- drivers/pci/probe.c | 14 +- include/linux/pci.h | 1 + 18 files changed, 368 insertions(+), 604 deletions(-) -- 2.25.1
