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)
