- 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)
