- Check only PCIE_LINKUP, not LTSSM status, to determine whether the link is up (Shawn Lin) - Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s for Root Complex and Endpoint modes (Shawn Lin) - Hide the broken ATS Capability in rockchip_pcie_ep_init() instead of rockchip_pcie_ep_pre_init() so it stays hidden after PERST# resets non-sticky registers (Shawn Lin) - Remove unused PCIE_CLIENT_GENERAL_DEBUG definition (Hans Zhang) - Organize register and bitfield definitions logically (Hans Zhang) - Use rockchip_pcie_link_up() to check link up instead of open coding, and use GENMASK() and FIELD_GET() when possible (Hans Zhang) - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit() (Diederik de Haas) - Return bool (not int) for link-up check in dw_pcie_ops.link_up() and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay, keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx, tegra194, uniphier, visconti (Hans Zhang) - Return bool (not int) for link-up check in mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans Zhang) - Simplify j721e link-up check (Hans Zhang) - Convert pci-host-common to a library so platforms that don't need native host controller drivers don't need to include these helper functions (Manivannan Sadhasivam) * pci/controller/dw-rockchip: PCI: qcom: Replace PERST# sleep time with proper macro PCI: dw-rockchip: Replace PERST# sleep time with proper macro PCI: host-common: Convert to library for host controller drivers PCI: cadence: Simplify J721e link status check PCI: mobiveil: Return bool from link up check PCI: dwc: Return bool from link up check PCI: dw-rockchip: Fix PHY function call sequence in rockchip_pcie_phy_deinit() PCI: dw-rockchip: Use rockchip_pcie_link_up() to check link up instead of open coding PCI: dw-rockchip: Reorganize register and bitfield definitions PCI: dw-rockchip: Remove unused PCIE_CLIENT_GENERAL_DEBUG definition PCI: dw-rockchip: Move rockchip_pcie_ep_hide_broken_ats_cap_rk3588() to dw_pcie_ep_ops::init() PCI: dw-rockchip: Enable ASPM L0s capability for both RC and EP modes PCI: dw-rockchip: Remove PCIE_L0S_ENTRY check from rockchip_pcie_link_up() # Conflicts: # drivers/pci/controller/pcie-apple.c # include/linux/pci-ecam.h
