This includes several Synopsys DesignWare eDMA controller driver changes
that are in drivers/dma, not drivers/pci. These lead up to eDMA support in
PCIe Root Port and Endpoint drivers and have been acked by Vinod.
The following changes since commit 1b929c02afd37871d5afb9d498426f83432e71c2:

Merge branch 'pci/misc' (2023-02-22 13:47:32 -0600)
----------------------------------------------------------------
Enumeration:
- Rework portdrv shutdown so it disables interrupts but doesn't disable
bus mastering, which leads to hangs on Loongson LS7A.
- Add mechanism to prevent Max_Read_Request_Size (MRRS) increases, again
to avoid hardware issues on Loongson LS7A (and likely other devices
based on DesignWare IP).
- Ignore devices with a firmware (DT or ACPI) node that says the device
is disabled.
Resource management:
- Distribute spare resources to unconfigured hotplug bridges at boot-time
(not just when hot-adding such a bridge), which makes hot-adding
devices to docks work better. Tried this in v6.1 but had to revert for
regressions, so try again.
- Fix root bus issue that dropped resources that happened to end at 0,
e.g., [bus 00].
PCI device hotplug:
- Remove device locking when marking device as disconnected so this
doesn't have to wait for concurrent driver bind/unbind to complete.
- Quirk more Qualcomm bridges that don't fully implement the PCIe Slot
Status 'Command Completed' bit.
Power management:
- Account for _S0W of the target bridge in acpi_pci_bridge_d3() so we
don't miss hot-add notifications for USB4 docks, Thunderbolt, etc.
Reset:
- Observe delay after reset, e.g., resuming from system sleep, regardless
of whether a bridge can suspend to D3cold at runtime.
- Wait for secondary bus to become ready after a bridge reset.
Virtualization:
- Avoid FLR on some AMD FCH AHCI adapters where it doesn't work.
- Allow independent IOMMU groups for some Wangxun NICs that prevent
peer-to-peer transactions but don't advertise an ACS Capability.
Error handling:
- Configure End-to-End-CRC (ECRC) only if Linux owns the AER Capability.
- Remove redundant Device Control Error Reporting Enable in the AER
service driver since this is already done for all devices during
enumeration.
ASPM:
- Add pci_enable_link_state() interface to allow drivers to enable ASPM
link state.
Endpoint framework:
- Move dra7xx and tegra194 linkup processing from hard IRQ to threaded
IRQ handler.
- Add a separate lock for endpoint controller list of endpoint function
drivers to prevent deadlock in callbacks.
- Pass events from endpoint controller to endpoint function drivers via
callbacks instead of notifiers.
Synopsys DesignWare eDMA controller driver (acked by Vinod):
- Fix CPU vs PCI address issues.
- Fix source vs destination address issues.
- Fix issues with interleaved transfer semantics.
- Fix channel count initialization issue (issue still exists in several
other drivers).
- Clean up and improve debugfs usage so it will work on platforms with
several eDMA devices.
Baikal T-1 PCIe controller driver:
- Set a 64-bit DMA mask.
Freescale i.MX6 PCIe controller driver:
- Add i.MX8MM, i.MX8MQ, i.MX8MP endpoint mode DT binding and driver
support.
Intel VMD host bridge driver:
- Add quirk to configure PCIe ASPM and LTR. This is normally done by
BIOS, and will be for future products.
Marvell MVEBU PCIe controller driver:
- Mark this driver as broken in Kconfig since bugs prevent its daily
usage.
MediaTek MT7621 PCIe controller driver:
- Delay PHY port initialization to improve boot reliability for ZBT
WE1326, ZBT WF3526-P, and some Netgear models.
Qualcomm PCIe controller driver:
- Add MSM8998 DT compatible string.
- Unify MSM8996 and MSM8998 clock orderings.
- Add SM8350 DT binding and driver support.
- Add IPQ8074 Gen3 DT binding and driver support.
- Correct qcom,perst-regs in DT binding.
- Add qcom_pcie_host_deinit() so the PHY is powered off and regulators
and clocks are disabled on late host-init errors.
Socionext UniPhier Pro5 controller driver:
- Clean up uniphier-ep reg, clocks, resets, and their names in DT
binding.
Synopsys DesignWare PCIe controller driver:
- Restrict coherent DMA mask to 32 bits for MSI, but allow controller
drivers to set 64-bit streaming DMA mask.
- Add eDMA engine support in both Root Port and Endpoint controllers.
Miscellaneous:
- Remove MODULE_LICENSE from boolean drivers so they don't look like
modules so modprobe can complain about them.
