Pull pci updates from Bjorn Helgaas:
"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.
- Revert to a BAR assignment inherited from firmware only when the
address is actually reachable via any upstream bridges, which fixes
some cases where firmware doesn't configure all devices.
- Add a sysfs interface to resize BARs so this can be done before
assigning devices to a VM through VFIO.
Power management:
- Disable Precision Time Management for all devices on suspend to
enable lower-power PM state. We previously did this just for Root
Ports, which isn't enough because downstream devices can still
generate PTM messages, which cause errors if it's disabled in the
Root Port.
- Save and restore the ASPM L1 PM Substates configuration for
suspend/ resume. Previously this configuration was lost, so L1.x
states likely stopped working after resume.
- Check whether the L1 PM Substates Capability exists. If it didn't
exist, we previously read junk and tried to configure L1 Substates
based on that.
- Fix the LTR_L1.2_THRESHOLD computation, which previously set a
threshold for entering L1.2 that was too low in some cases.
- Reduce the delay after transitions to or from D3cold by using
usleep_range() rather than msleep(), which often slept for ~19ms
instead of the 10ms normally required. The spec says 10ms is
enough, but it's possible we could trip over devices that need a
little more.
Error handling:
- Work around a BIOS bug that caused Intel Root Ports to advertise a
Root Port Programmed I/O (RP PIO) log size of zero, which caused
annoying warnings and prevented the kernel from dumping log
registers for DPC errors.
Qualcomm PCIe controller driver:
- Add support for SC8280XP and SA8540P host controllers and SM8450
endpoint controller.
- Disable Master AXI clock on endpoint controllers to save power when
link is idle or in L1.x.
- Expose link state transition counts via debugfs to help debug
issues with low-power states.
- Add auto-loading module support.
Synopsys DesignWare PCIe controller driver:
- Remove a dependency on ZONE_DMA32 by allocating the MSI target page
differently. There's more work to do related to eDMA controllers,
so it's not completely settled"

Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1.
Nothing major in here, lots of little things with new devices supported
and updates for a few drivers. Highlights include:
- thunderbolt/USB4 devices supported a bit better than before,
and some new ids to enable new hardware devices
- USB gadget uvc updates for newer video formats and better v4l
integration (the v4l portions were acked by those maintainers)
- typec updates for tiny issues and more typec drivers for new
chips.
- xhci tiny updates for minor issues
- big usb-serial ftdi_sio driver update to handle new devices
better
- lots of tiny dwc3 fixes and updates for the IP block that is
showing up everywhere these days
- dts updates for new devices being supported
- other tiny janitorial and cleanups fixes for lots of different
USB drivers. Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

The drivers branch for 6.1 is a bit larger than for most releases. Most
of the changes come from SoC maintainers for the drivers/soc subsystem:
- A new driver for error handling on the NVIDIA Tegra
'control backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip
SoCs, various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM
driver, the Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
Tegra, Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers that
merge updates this way:
- Various updates and new drivers in the memory controller
subsystem for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A
v1.1 specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem

RX registers. Since the commit 4be26f695f ("phy: qcom-qmp-pcie: fix

which will check if error code is -EPROBE_DEFER and prints the
