Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Batch sizing of multiple BARs while memory decoding is disabled
     instead of disabling/enabling decoding for each BAR individually;
     this optimizes virtualized environments where toggling decoding
     enable is expensive (Alex Williamson)

   - Add host bridge .enable_device() and .disable_device() hooks for
     bridges that need to configure things like Requester ID to StreamID
     mapping when enabling devices (Frank Li)

   - Extend struct pci_ecam_ops with .enable_device() and
     .disable_device() hooks so drivers that use pci_host_common_probe()
     instead of their own .probe() have a way to set the
     .enable_device() callbacks (Marc Zyngier)

   - Drop 'No bus range found' message so we don't complain when DTs
     don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas)

   - Rename the drivers/pci/of_property.c struct of_pci_range to
     of_pci_range_entry to avoid confusion with the global of_pci_range
     in include/linux/of_address.h (Bjorn Helgaas)

  Driver binding:

   - Update resource request API documentation to encourage callers to
     supply a driver name when requesting resources (Philipp Stanner)

   - Export pci_intx_unmanaged() and pcim_intx() (always managed) so
     callers of pci_intx() (which is sometimes managed) can explicitly
     choose the one they need (Philipp Stanner)

   - Convert drivers from pci_intx() to always-managed pcim_intx() or
     never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
     pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna,
     ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)

   - Remove pci_intx_unmanaged() since pci_intx() is now always
     unmanaged and pcim_intx() is always managed (Philipp Stanner)

  Error handling:

   - Unexport pcie_read_tlp_log() to encourage drivers to use PCI core
     logging rather than building their own (Ilpo Järvinen)

   - Move TLP Log handling to its own file (Ilpo Järvinen)

   - Store number of supported End-End TLP Prefixes always so we can
     read the correct number of DWORDs from the TLP Prefix Log (Ilpo
     Järvinen)

   - Read TLP Prefixes in addition to the Header Log in
     pcie_read_tlp_log() (Ilpo Järvinen)

   - Add pcie_print_tlp_log() to consolidate printing of TLP Header and
     Prefix Log (Ilpo Järvinen)

   - Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor
     BIOSes that don't configure it correctly (Takashi Iwai)

  ASPM:

   - Save parent L1 PM Substates config so when we restore it along with
     an endpoint's config, the parent info isn't junk (Jian-Hong Pan)

  Power management:

   - Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because
     the system can't wake up from suspend (Werner Sembach)

  Endpoint framework:

   - Destroy the EPC device in devm_pci_epc_destroy(), which previously
     didn't call devres_release() (Zijun Hu)

   - Finish virtual EP removal in pci_epf_remove_vepf(), which
     previously caused a subsequent pci_epf_add_vepf() to fail with
     -EBUSY (Zijun Hu)

   - Write BAR_MASK before iATU registers in pci_epc_set_bar() so we
     don't depend on the BAR_MASK reset value being larger than the
     requested BAR size (Niklas Cassel)

   - Prevent changing BAR size/flags in pci_epc_set_bar() to prevent
     reads from bypassing the iATU if we reduced the BAR size (Niklas
     Cassel)

   - Verify address alignment when programming iATU so we don't attempt
     to write bits that are read-only because of the BAR size, which
     could lead to directing accesses to the wrong address (Niklas
     Cassel)

   - Implement artpec6 pci_epc_features so we can rely on all drivers
     supporting it so we can use it in EPC core code (Niklas Cassel)

   - Check for BARs of fixed size to prevent endpoint drivers from
     trying to change their size (Niklas Cassel)

   - Verify that requested BAR size is a power of two when endpoint
     driver sets the BAR (Niklas Cassel)

  Endpoint framework tests:

   - Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing
     dma_chan_rx (Mohamed Khalfella)

   - Correct the DMA MEMCPY test so it doesn't fail if the Endpoint
     supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam)

   - Add pci-epf-test and pci_endpoint_test support for capabilities
     (Niklas Cassel)

   - Add Endpoint test for consecutive BARs (Niklas Cassel)

   - Remove redundant comparison from Endpoint BAR test because a > 1MB
     BAR can always be exactly covered by iterating with a 1MB buffer
     (Hans Zhang)

   - Move and convert PCI Endpoint tests from tools/pci to Kselftests
     (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Convert StreamID mapping configuration from a bus notifier to the
     .enable_device() and .disable_device() callbacks (Marc Zyngier)

  Freescale i.MX6 PCIe controller driver:

   - Add Requester ID to StreamID mapping configuration when enabling
     devices (Frank Li)

   - Use DWC core suspend/resume functions for imx6 (Frank Li)

   - Add suspend/resume support for i.MX8MQ, i.MX8Q, and i.MX95 (Richard
     Zhu)

   - Add DT compatible string 'fsl,imx8q-pcie-ep' and driver support for
     i.MX8Q series (i.MX8QM, i.MX8QXP, and i.MX8DXL) Endpoints (Frank
     Li)

   - Add DT binding for optional i.MX95 Refclk and driver support to
     enable it if the platform hasn't enabled it (Richard Zhu)

   - Configure PHY based on controller being in Root Complex or Endpoint
     mode (Frank Li)

   - Rely on dbi2 and iATU base addresses from DT via
     dw_pcie_get_resources() instead of hardcoding them (Richard Zhu)

   - Deassert apps_reset in imx_pcie_deassert_core_reset() since it is
     asserted in imx_pcie_assert_core_reset() (Richard Zhu)

   - Add missing reference clock enable or disable logic for IMX6SX,
     IMX7D, IMX8MM (Richard Zhu)

   - Remove redundant imx7d_pcie_init_phy() since
     imx7d_pcie_enable_ref_clk() does the same thing (Richard Zhu)

  Freescale Layerscape PCIe controller driver:

   - Simplify by using syscon_regmap_lookup_by_phandle_args() instead
     of syscon_regmap_lookup_by_phandle() followed by
     of_property_read_u32_array() (Krzysztof Kozlowski)

  Marvell MVEBU PCIe controller driver:

   - Add MODULE_DEVICE_TABLE() to enable module autoloading (Liao Chen)

  MediaTek PCIe Gen3 controller driver:

   - Use clk_bulk_prepare_enable() instead of separate
     clk_bulk_prepare() and clk_bulk_enable() (Lorenzo Bianconi)

   - Rearrange reset assert/deassert so they're both done in the
     *_power_up() callbacks (Lorenzo Bianconi)

   - Document that Airoha EN7581 requires PHY init and power-on before
     PHY reset deassert, unlike other MediaTek Gen3 controllers (Lorenzo
     Bianconi)

   - Move Airoha EN7581 post-reset delay from the en7581 clock .enable()
     method to mtk_pcie_en7581_power_up() (Lorenzo Bianconi)

   - Sleep instead of delay during Airoha EN7581 power-up, since this is
     a non-atomic context (Lorenzo Bianconi)

   - Skip PERST# assertion on Airoha EN7581 during probe and
     suspend/resume to avoid a hardware defect (Lorenzo Bianconi)

   - Enable async probe to reduce system startup time (Douglas Anderson)

  Microchip PolarFlare PCIe controller driver:

   - Set up the inbound address translation based on whether the
     platform allows coherent or non-coherent DMA (Daire McNamara)

   - Update DT binding such that platforms are DMA-coherent by default
     and must specify 'dma-noncoherent' if needed (Conor Dooley)

  Mobiveil PCIe controller driver:

   - Convert mobiveil-pcie.txt to YAML and update 'interrupt-names'
     and 'reg-names' (Frank Li)

  Qualcomm PCIe controller driver:

   - Add DT SM8550 and SM8650 optional 'global' interrupt for link
     events (Neil Armstrong)

   - Add DT 'compatible' strings for IPQ5424 PCIe controller (Manikanta
     Mylavarapu)

   - If 'global' IRQ is supported for detection of Link Up events, tell
     DWC core not to wait for link up (Krishna chaitanya chundru)

  Renesas R-Car PCIe controller driver:

   - Avoid passing stack buffer as resource name (King Dix)

  Rockchip PCIe controller driver:

   - Simplify clock and reset handling by using bulk interfaces (Anand
     Moon)

   - Pass typed rockchip_pcie (not void) pointer to
     rockchip_pcie_disable_clocks() (Anand Moon)

   - Return -ENOMEM, not success, when pci_epc_mem_alloc_addr() fails
     (Dan Carpenter)

  Rockchip DesignWare PCIe controller driver:

   - Use dll_link_up IRQ to detect Link Up and enumerate devices so
     users don't have to manually rescan (Niklas Cassel)

   - Tell DWC core not to wait for link up since the 'sys' interrupt is
     required and detects Link Up events (Niklas Cassel)

  Synopsys DesignWare PCIe controller driver:

   - Don't wait for link up in DWC core if driver can detect Link Up
     event (Krishna chaitanya chundru)

   - Update ICC and OPP votes after Link Up events (Krishna chaitanya
     chundru)

   - Always stop link in dw_pcie_suspend_noirq(), which is required at
     least for i.MX8QM to re-establish link on resume (Richard Zhu)

   - Drop racy and unnecessary LTSSM state check before sending
     PME_TURN_OFF message in dw_pcie_suspend_noirq() (Richard Zhu)

   - Add struct of_pci_range.parent_bus_addr for devices that need their
     immediate parent bus address, not the CPU address, e.g., to program
     an internal Address Translation Unit (iATU) (Frank Li)

  TI DRA7xx PCIe controller driver:

   - Simplify by using syscon_regmap_lookup_by_phandle_args() instead of
     syscon_regmap_lookup_by_phandle() followed by
     of_parse_phandle_with_fixed_args() or of_property_read_u32_index()
     (Krzysztof Kozlowski)

   - Add DT binding and driver support for Xilinx Versal CPM5
     (Thippeswamy Havalige)

   - Move reset related sysfs code from pci.c to pci-sysfs.c where other
     similar code lives (Ilpo Järvinen)

   - Simplify reset_method_store() memory management by using __free()
     instead of explicit kfree() cleanup (Ilpo Järvinen)

   - Constify struct bin_attribute for sysfs, VPD, P2PDMA, and the IBM

-NXP Layerscape PCIe Gen4 controller
-
-This PCIe controller is based on the Mobiveil PCIe IP and thus inherits all
-the common properties defined in mobiveil-pcie.txt.
-
-Required properties:
-- compatible: should contain the platform identifier such as:
-  "fsl,lx2160a-pcie"
-- reg: base addresses and lengths of the PCIe controller register blocks.
-  "csr_axi_slave": Bridge config registers
-  "config_axi_slave": PCIe controller registers
-- interrupts: A list of interrupt outputs of the controller. Must contain an
-  entry for each entry in the interrupt-names property.
-- interrupt-names: It could include the following entries:
-  "intr": The interrupt that is asserted for controller interrupts
-  "aer": Asserted for aer interrupt when chip support the aer interrupt with
-	 none MSI/MSI-X/INTx mode,but there is interrupt line for aer.
-  "pme": Asserted for pme interrupt when chip support the pme interrupt with
-	 none MSI/MSI-X/INTx mode,but there is interrupt line for pme.
-- dma-coherent: Indicates that the hardware IP block can ensure the coherency
-  of the data transferred from/to the IP block. This can avoid the software
-  cache flush/invalid actions, and improve the performance significantly.
-- msi-parent : See the generic MSI binding described in
-  Documentation/devicetree/bindings/interrupt-controller/msi.txt.

-* Mobiveil AXI PCIe Root Port Bridge DT description
-
-Mobiveil's GPEX 4.0 is a PCIe Gen4 root port bridge IP. This configurable IP
-has up to 8 outbound and inbound windows for the address translation.
-
-Required properties:
-- #address-cells: Address representation for root ports, set to <3>
-- #size-cells: Size representation for root ports, set to <2>
-- #interrupt-cells: specifies the number of cells needed to encode an
-	interrupt source. The value must be 1.
-- compatible: Should contain "mbvl,gpex40-pcie"
-- reg: Should contain PCIe registers location and length
-	Mandatory:
-	"config_axi_slave": PCIe controller registers
-	"csr_axi_slave"	  : Bridge config registers
-	Optional:
-	"gpio_slave"	  : GPIO registers to control slot power
-	"apb_csr"	  : MSI registers
-
-- device_type: must be "pci"
-- apio-wins : number of requested apio outbound windows
-		default 2 outbound windows are configured -
-		1. Config window
-		2. Memory window
-- ppio-wins : number of requested ppio inbound windows
-		default 1 inbound memory window is configured.
-- bus-range: PCI bus numbers covered
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: specifies the number of cells needed to encode an
-	interrupt source. The value must be 1.
-- interrupts: The interrupt line of the PCIe controller
-		last cell of this field is set to 4 to
-		denote it as IRQ_TYPE_LEVEL_HIGH type interrupt.
-- interrupt-map-mask,
-	interrupt-map: standard PCI properties to define the mapping of the
-	PCI interface to interrupt numbers.
-- ranges: ranges for the PCI memory regions (I/O space region is not
-	supported by hardware)
-	Please refer to the standard PCI bus binding document for a more
-	detailed explanation
-
