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) -
