Merge branch 'pci/ctrl/dwc'

- Stop link on host_init errors and de-initialization (Serge Semin)

- Add support for unrolled iATU register space in dw_pcie_disable_atu()
  (Serge Semin)

- Disable outbound windows only for controllers that use iATU (Serge Semin)

- Set INCREASE_REGION_SIZE flag based on limit address, not on the size,
  since even a small size may cross a 4GB boundary (Serge Semin)

- Deallocate EPC memory on dw_pcie_ep_init() errors to avoid a leak (Serge
  Semin)

- Always enable CDM check if "snps,enable-cdm-check" exists instead of
  exiting early if the optional "num-lanes" was absent (Serge Semin)

- Simplify detection of whether we're using unrolled iATU registers (Serge
  Semin)

- Make dw_pcie_link_up() more generic by using dw_pcie_readl_dbi() instead
  of readl() (Serge Semin)

- Add dw_pcie_start_link() and dw_pcie_stop_link() wrappers to factor out
  checks for ops being implemented (Serge Semin)

- Move io_cfg_atu_shared to struct pcie_port and rename to cfg0_io_shared,
  since it's not used by dwc common code or dwc endpoint code (Serge Semin)

- Rename struct pcie_port to dw_pcie_rp to indicate that it's
  DesignWare-specific (Serge Semin)

- Drop unused struct dw_plat_pcie regmap pointer (Serge Semin)

- Fix some coding style issues (Serge Semin)

- Log link speed and width if it comes up (Serge Semin)

- Save DWC IP core version in native format as read from
  PORT_LOGIC.PCIE_VERSION_OFF register (Serge Semin)

- Read DWC IP core version from PORT_LOGIC.PCIE_VERSION_OFF (Serge Semin)

- Add macros to compare Synopsys IP core versions (Serge Semin)

- Drop manual DWC IP core version setup from intel-gw and tegra194 (Serge
  Semin)

- Add dw_pcie_ops.host_deinit() callback (Serge Semin)

- Drop enum dw_pcie_as_type in favor of PCIE_ATU_TYPE_MEM/IO (Serge Semin)

- Drop enum dw_pcie_region_type in favor of PCIE_ATU_REGION_DIR_IB/OB
  (Serge Semin)

- Simplify in/outbound iATU setup methods and reduce duplicated code (Serge
  Semin)

- Detect iATU region size from hardware (Serge Semin)

- Validate iATU outbound mappings against hardware constraints (Serge
  Semin)

- Check for errors in iATU setup (Serge Semin)

- Allocate a 32-bit DMA-able page to be MSI target instead of using a
  driver data structure that may not be addressable with 32-bit address
  (Will McVicker)

- Use the bitmap API to allocate bitmaps instead of open-coding it
  (Christophe JAILLET)

- Correct dw_pcie_free_msi() checking for when to remove IRQ handler and
  data (Dmitry Baryshkov)

- Split MSI init to new dw_pcie_msi_host_init() function (Dmitry Baryshkov)

- Convert struct pcie_port.msi_irq to an array so we can support more than
  32 MSI interrupts (Dmitry Baryshkov)

- Handle MSIs routed to multiple GIC interrupts for Qualcomm platforms with
  groups of 32 MSI vectors (Dmitry Baryshkov)

- Add additional MSI interrupts to qcom DT (Dmitry Baryshkov)
