Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Consolidate duplicated 'next function' scanning and extend to allow
     'isolated functions' on s390, similar to existing hypervisors
     (Niklas Schnelle)

  Resource management:
   - Implement pci_iobar_pfn() for sparc, which allows us to remove the
     sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().

     This removes the ability to map the entire PCI I/O space using
     /proc/bus/pci, but we believe that's already been broken since
     v2.6.28 (Arnd Bergmann)

   - Move common PCI definitions to asm-generic/pci.h and rework others
     to be be more specific and more encapsulated in arches that need
     them (Stafford Horne)

  Power management:

   - Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef
     CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)

  Virtualization:

   - Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate
     the functions but don't advertise an ACS capability (Pavan Chebbi)

  Error handling:

   - Clear PCI Status register during enumeration in case firmware left
     errors logged (Kai-Heng Feng)

   - When we have native control of AER, enable error reporting for all
     devices that support AER. Previously only a few drivers enabled
     this (Stefan Roese)

   - Keep AER error reporting enabled for switches. Previously we
     enabled this during enumeration but immediately disabled it (Stefan
     Roese)

   - Iterate over error counters instead of error strings to avoid
     printing junk in AER sysfs counters (Mohamed Khalfella)

  ASPM:

   - Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g.,
     via sysfs, are not lost across power state changes (Kai-Heng Feng)

  Endpoint framework:

   - Don't stop an EPC when unbinding an EPF from it (Shunsuke Mie)

  Endpoint embedded DMA controller driver:

   - Simplify and clean up support for the DesignWare embedded DMA
     (eDMA) controller (Frank Li, Serge Semin)

  Broadcom STB PCIe controller driver:

   - Avoid config space accesses when link is down because we can't
     recover from the CPU aborts these cause (Jim Quinlan)

   - Look for power regulators described under Root Ports in DT and
     enable them before scanning the secondary bus (Jim Quinlan)

   - Disable/enable regulators in suspend/resume (Jim Quinlan)

  Freescale i.MX6 PCIe controller driver:

   - Simplify and clean up clock and PHY management (Richard Zhu)

   - Disable/enable regulators in suspend/resume (Richard Zhu)

   - Set PCIE_DBI_RO_WR_EN before writing DBI registers (Richard Zhu)

   - Allow speeds faster than Gen2 (Richard Zhu)

   - Make link being down a non-fatal error so controller probe doesn't
     fail if there are no Endpoints connected (Richard Zhu)

  Loongson PCIe controller driver:

   - Add ACPI and MCFG support for Loongson LS7A (Huacai Chen)

   - Avoid config reads to non-existent LS2K/LS7A devices because a
     hardware defect causes machine hangs (Huacai Chen)

   - Work around LS7A integrated devices that report incorrect Interrupt
     Pin values (Jianmin Lv)

  Marvell Aardvark PCIe controller driver:

   - Add support for AER and Slot capability on emulated bridge (Pali
     Rohár)

  MediaTek PCIe controller driver:

   - Add Airoha EN7532 to DT binding (John Crispin)

   - Allow building of driver for ARCH_AIROHA (Felix Fietkau)

  MediaTek PCIe Gen3 controller driver:

   - Print decoded LTSSM state when the link doesn't come up (Jianjun
     Wang)

  NVIDIA Tegra194 PCIe controller driver:

   - Convert DT binding to json-schema (Vidya Sagar)

   - Add DT bindings and driver support for Tegra234 Root Port and
     Endpoint mode (Vidya Sagar)

   - Fix some Root Port interrupt handling issues (Vidya Sagar)

   - Set default Max Payload Size to 256 bytes (Vidya Sagar)

   - Fix Data Link Feature capability programming (Vidya Sagar)

   - Extend Endpoint mode support to devices beyond Controller-5 (Vidya
     Sagar)

  Qualcomm PCIe controller driver:

   - Rework clock, reset, PHY power-on ordering to avoid hangs and
     improve consistency (Robert Marko, Christian Marangi)

   - Move pipe_clk handling to PHY drivers (Dmitry Baryshkov)

   - Add IPQ60xx support (Selvam Sathappan Periakaruppan)

   - Allow ASPM L1 and substates for 2.7.0 (Krishna chaitanya chundru)

   - Add support for more than 32 MSI interrupts (Dmitry Baryshkov)

  Renesas R-Car PCIe controller driver:

   - Convert DT binding to json-schema (Herve Codina)

   - Add Renesas RZ/N1D (R9A06G032) to rcar-gen2 DT binding and driver
     (Herve Codina)

  Samsung Exynos PCIe controller driver:

   - Fix phy-exynos-pcie driver so it follows the 'phy_init() before
     phy_power_on()' PHY programming model (Marek Szyprowski)

  Synopsys DesignWare PCIe controller driver:

   - Simplify and clean up the DWC core extensively (Serge Semin)

   - Fix an issue with programming the ATU for regions that cross a 4GB
     boundary (Serge Semin)

   - Enable the CDM check if 'snps,enable-cdm-check' exists; previously
     we skipped it if 'num-lanes' was absent (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)

   - Add DWC core support for more than 32 MSI interrupts (Dmitry
     Baryshkov)

  Xilinx Versal CPM PCIe controller driver:

   - Add DT binding and driver support for Versal CPM5 Gen5 Root Port
     (Bharat Kumar Gogada)"

+
+description: |
+  This PCIe controller is based on the Synopsys DesignWare PCIe IP and thus
+  inherits all the common properties defined in snps,dw-pcie-ep.yaml.  Some
+  of the controller instances are dual mode; they can work either in Root
+  Port mode or Endpoint mode but one at a time.
+
+  On Tegra194, controllers C0, C4 and C5 support Endpoint mode.
+  On Tegra234, controllers C5, C6, C7 and C10 support Endpoint mode.
+
+  Note: On Tegra194's P2972-0000 platform, only C5 controller can be enabled to
+  operate in the Endpoint mode because of the way the platform is designed.

-NVIDIA Tegra PCIe controller (Synopsys DesignWare Core based)
-
-This PCIe controller is based on the Synopsis Designware PCIe IP
-and thus inherits all the common properties defined in snps,dw-pcie.yaml and
-snps,dw-pcie-ep.yaml.
-Some of the controller instances are dual mode where in they can work either
-in root port mode or endpoint mode but one at a time.
-
-Required properties:
-- power-domains: A phandle to the node that controls power to the respective
-  PCIe controller and a specifier name for the PCIe controller. Following are
-  the specifiers for the different PCIe controllers
-    TEGRA194_POWER_DOMAIN_PCIEX8B: C0
-    TEGRA194_POWER_DOMAIN_PCIEX1A: C1
-    TEGRA194_POWER_DOMAIN_PCIEX1A: C2
-    TEGRA194_POWER_DOMAIN_PCIEX1A: C3
-    TEGRA194_POWER_DOMAIN_PCIEX4A: C4
-    TEGRA194_POWER_DOMAIN_PCIEX8A: C5
-  these specifiers are defined in
-  "include/dt-bindings/power/tegra194-powergate.h" file.
-- reg: A list of physical base address and length pairs for each set of
-  controller registers. Must contain an entry for each entry in the reg-names
-  property.
-- reg-names: Must include the following entries:
-  "appl": Controller's application logic registers
-  "config": As per the definition in snps,dw-pcie.yaml
-  "atu_dma": iATU and DMA registers. This is where the iATU (internal Address
-             Translation Unit) registers of the PCIe core are made available
-             for SW access.
-  "dbi": The aperture where root port's own configuration registers are
-         available
-- interrupts: A list of interrupt outputs of the controller. Must contain an
-  entry for each entry in the interrupt-names property.
-- interrupt-names: Must include the following entries:
-  "intr": The Tegra interrupt that is asserted for controller interrupts
-- clocks: Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
-  - core
-- resets: Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names: Must include the following entries:
-  - apb
-  - core
-- phys: Must contain a phandle to P2U PHY for each entry in phy-names.
-- phy-names: Must include an entry for each active lane.
-  "p2u-N": where N ranges from 0 to one less than the total number of lanes
-- nvidia,bpmp: Must contain a pair of phandle to BPMP controller node followed
-  by controller-id. Following are the controller ids for each controller.
-    0: C0
-    1: C1
-    2: C2
-    3: C3
-    4: C4
-    5: C5
-- vddio-pex-ctl-supply: Regulator supply for PCIe side band signals
-
-RC mode:
-- compatible: Tegra19x must contain  "nvidia,tegra194-pcie"
-- device_type: Must be "pci" for RC mode
-- interrupt-names: Must include the following entries:
-  "msi": The Tegra interrupt that is asserted when an MSI is received
-- bus-range: Range of bus numbers associated with this controller
-- #address-cells: Address representation for root ports (must be 3)
-  - cell 0 specifies the bus and device numbers of the root port:
-    [23:16]: bus number
-    [15:11]: device number
-  - cell 1 denotes the upper 32 address bits and should be 0
-  - cell 2 contains the lower 32 address bits and is used to translate to the
-    CPU address space
-- #size-cells: Size representation for root ports (must be 2)
-- ranges: Describes the translation of addresses for root ports and standard
-  PCI regions. The entries must be 7 cells each, where the first three cells
-  correspond to the address as described for the #address-cells property
-  above, the fourth and fifth cells are for the physical CPU address to
-  translate to and the sixth and seventh cells are as described for the
-  #size-cells property above.
-  - Entries setup the mapping for the standard I/O, memory and
-    prefetchable PCI regions. The first cell determines the type of region
-    that is setup:
-    - 0x81000000: I/O memory region
-    - 0x82000000: non-prefetchable memory region
-    - 0xc2000000: prefetchable memory region
-  Please refer to the standard PCI bus binding document for a more detailed
-  explanation.
-- #interrupt-cells: Size representation for interrupts (must be 1)
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties

-- pinctrl-0: phandle for the 'default' state of pin configuration.
-  It is mandatory for C5 controller and optional for other controllers.
-- supports-clkreq: Refer to Documentation/devicetree/bindings/pci/pci.txt
-- nvidia,update-fc-fixup: This is a boolean property and needs to be present to
-    improve performance when a platform is designed in such a way that it
-    satisfies at least one of the following conditions thereby enabling root
-    port to exchange optimum number of FC (Flow Control) credits with
-    downstream devices
-    1. If C0/C4/C5 run at x1/x2 link widths (irrespective of speed and MPS)
-    2. If C0/C1/C2/C3/C4/C5 operate at their respective max link widths and
-       a) speed is Gen-2 and MPS is 256B

-  if the platform has one such slot. (Ex:- x16 slot owned by C5 controller
-  in p2972-0000 platform).
-
-EP mode:
-- nvidia,refclk-select-gpios: Must contain a phandle to a GPIO controller
-  followed by GPIO that is being used to enable REFCLK to controller from host
-
-NOTE:- On Tegra194's P2972-0000 platform, only C5 controller can be enabled to
-operate in the endpoint mode because of the way the platform is designed.

-Renesas AHB to PCI bridge
--------------------------
-
-This is the bridge used internally to connect the USB controllers to the
-AHB. There is one bridge instance per USB port connected to the internal
-OHCI and EHCI controllers.
-
-Required properties:
-- compatible: "renesas,pci-r8a7742" for the R8A7742 SoC;
-	      "renesas,pci-r8a7743" for the R8A7743 SoC;
-	      "renesas,pci-r8a7744" for the R8A7744 SoC;
-	      "renesas,pci-r8a7745" for the R8A7745 SoC;
-	      "renesas,pci-r8a7790" for the R8A7790 SoC;
-	      "renesas,pci-r8a7791" for the R8A7791 SoC;
-	      "renesas,pci-r8a7793" for the R8A7793 SoC;
-	      "renesas,pci-r8a7794" for the R8A7794 SoC;
-	      "renesas,pci-rcar-gen2" for a generic R-Car Gen2 or
-				      RZ/G1 compatible device.
-
-
-	      When compatible with the generic version, nodes must list the
-	      SoC-specific version corresponding to the platform first
-	      followed by the generic version.
-
-- reg:	A list of physical regions to access the device: the first is
-	the operational registers for the OHCI/EHCI controllers and the
-	second is for the bridge configuration and control registers.
-- interrupts: interrupt for the device.
-- clocks: The reference to the device clock.
-- bus-range: The PCI bus number range; as this is a single bus, the range
-	     should be specified as the same value twice.
-- #address-cells: must be 3.
-- #size-cells: must be 2.
-- #interrupt-cells: must be 1.
-- interrupt-map: standard property used to define the mapping of the PCI
-  interrupts to the GIC interrupts.
-- interrupt-map-mask: standard property that helps to define the interrupt
-  mapping.
-
-Optional properties:
-- dma-ranges: a single range for the inbound memory region. If not supplied,
-  defaults to 1GiB at 0x40000000. Note there are hardware restrictions on the
-  allowed combinations of address and size.
-
-Example SoC configuration:
-
-	pci0: pci@ee090000  {
-		compatible = "renesas,pci-r8a7790", "renesas,pci-rcar-gen2";
-		clocks = <&mstp7_clks R8A7790_CLK_EHCI>;
-		reg = <0x0 0xee090000 0x0 0xc00>,
-		      <0x0 0xee080000 0x0 0x1100>;
-		interrupts = <0 108 IRQ_TYPE_LEVEL_HIGH>;
-		status = "disabled";
-
-		bus-range = <0 0>;
-		#address-cells = <3>;
-		#size-cells = <2>;
-		#interrupt-cells = <1>;
-		dma-ranges = <0x42000000 0 0x40000000 0 0x40000000 0 0x40000000>;
-		interrupt-map-mask = <0xff00 0 0 0x7>;
-		interrupt-map = <0x0000 0 0 1 &gic 0 108 IRQ_TYPE_LEVEL_HIGH
-				 0x0800 0 0 1 &gic 0 108 IRQ_TYPE_LEVEL_HIGH
-				 0x1000 0 0 2 &gic 0 108 IRQ_TYPE_LEVEL_HIGH>;
-
-		usb@1,0 {
-			reg = <0x800 0 0 0 0>;
-			phys = <&usb0 0>;
-			phy-names = "usb";
-		};
-
-		usb@2,0 {
-			reg = <0x1000 0 0 0 0>;
-			phys = <&usb0 0>;
-			phy-names = "usb";
-		};
-	};
-
-Example board setup:
-
-&pci0 {
-	status = "okay";
-	pinctrl-0 = <&usb0_pins>;
-	pinctrl-names = "default";
-};
