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)"
