In order to estimate when fs/ls transactions appear on a downstream bus,
the host must calculate a best case full-speed budget, use a table to
track how many bytes occure in each microframe.
This patch is prepared for introducing an improved bandwidth scheduling.

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. With the AMD quirk handled USB PCI quirks still use
inw() in uhci_check_and_reset_hc() and thus indirectly in
quirk_usb_handoff_uhci(). Handle this by conditionally compiling
uhci_check_and_reset_hc() and stubbing out quirk_usb_handoff_uhci() when
HAS_IOPORT is not available.

A follow on patch will introduce CONFIG_USB_PCI_AMD governing the AMD
quirk and adding its compile time dependency on HAS_IOPORT. In order to
minimize the number of #ifdefs in C files and make that patch easier
to read first group the code together. This is pure code movement
no functional change is intended.

DWC3 driver needs access to XHCI Extended Capabilities registers to

Pull tty/serial driver updates from Greg KH:
"Here is the big set of tty and serial driver changes for 6.6-rc1.
Lots of cleanups in here this cycle, and some driver updates. Short
summary is:
- Jiri's continued work to make the tty code and apis be a bit more
sane with regards to modern kernel coding style and types
- cpm_uart driver updates
- n_gsm updates and fixes
- meson driver updates
- sc16is7xx driver updates
- 8250 driver updates for different hardware types
- qcom-geni driver fixes
- tegra serial driver change
- stm32 driver updates
- synclink_gt driver cleanups
- tty structure size reduction
All of these have been in linux-next this week with no reported
issues. The last bit of cleanups from Jiri and the tty structure size
reduction came in last week, a bit late but as they were just style
changes and size reductions, I figured they should get into this merge
cycle so that others can work on top of them with no merge conflicts"

If initially isoc_count = 0, periodic_count > 0 and the io watchdog is
not started (e.g. just timed out), then the io watchdog may not run after
submitting isoc urbs and enable_periodic(). The isoc urbs may not complete
forever if the controller had already stopped periodic schedule.
This will try to call turn_on_io_watchdog() for each enable_periodic() to
ensure the io watchdog functions properly.

Wireless USB has long been defunct, and kernel support for it was
removed in 2020 by commit caa6772db4c1 ("Staging: remove wusbcore and
UWB from the kernel tree.").
Nevertheless, some vestiges of the old implementation still clutter up
the USB subsystem and one or two other places. Let's get rid of them
once and for all.
The only parts still left are the user-facing APIs in
include/uapi/linux/usb/ch9.h. (There are also a couple of misleading
instances, such as the Sierra Wireless USB modem, which is a USB modem
made by Sierra Wireless.)

Some NXP processor using chipidea IP has a bug when frame babble is
detected.
As per 4.15.1.1.1 Serial Bus Babble:
A babble condition also exists if IN transaction is in progress at
High-speed SOF2 point. This is called frame babble. The host controller
must disable the port to which the frame babble is detected.
The USB controller has disabled the port (PE cleared) and has asserted
USBERRINT when frame babble is detected, but PEC is not asserted.
Therefore, the SW isn't aware that port has been disabled. Then the
SW keeps sending packets to this port, but all of the transfers will
fail.
This workaround will firstly assert PCD by SW when USBERRINT is detected
and then judge whether port change has really occurred or not by polling
roothub status. Because the PEC doesn't get asserted in our case, this
patch will also assert it by SW when specific conditions are satisfied.

The ohci_hcd_at91_drv_suspend() sets ohci->rh_state to OHCI_RH_HALTED when
suspend which will let the ohci_irq() skip the interrupt after resume. And
nobody to handle this interrupt.
According to the comment in ohci_hcd_at91_drv_suspend(), it need to reset
when resume from suspend(MEM) to fix by setting "hibernated" argument of
ohci_resume().

If memory accesses by the Tegra XUSB controller are translated through
the SMMU (System MMU), the hardware may continue accessing memory even
after the SMMU translations have been disabled during the shutdown

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

This reverts commit 18fc7c435be3f17ea26a21b2e2312fcb9088e01f.
The reverted commit was based on static analysis and a misunderstanding
of how PTR_ERR() and NULLs are supposed to work. When a function
returns both pointer errors and NULL then normally the NULL means
"continue operating without a feature because it was deliberately
turned off". The NULL should not be treated as a failure. If a driver
cannot work when that feature is disabled then the KConfig should
enforce that the function cannot return NULL. We should not need to
test for it.
In this code, the patch means that certain tegra_xusb_probe() will
fail if the firmware supports power-domains but CONFIG_PM is disabled.

The hardware in question is an external PCIe card. It looks to me like the quirk
needs to be narrowed down. But this needs information about the hardware showing
the issue this quirk is to fix. So for now a clean revert.

Allow devices to have dma operations beyond 64K, and avoid warnings such
as:

The ohci_hcd_at91_drv_suspend() sets ohci->rh_state to OHCI_RH_HALTED when
suspend which will let the ohci_irq() skip the interrupt after resume. And
nobody to handle this interrupt.
According to the comment in ohci_hcd_at91_drv_suspend(), it need to reset
when resume from suspend(MEM) to fix by setting "hibernated" argument of
ohci_resume().

Pull USB / Thunderbolt driver updates from Greg KH:
"Here is the big set of USB and Thunderbolt driver updates for 6.5-rc1.
Included in here are:
- Lots of USB4/Thunderbolt additions and updates for new hardware
types and fixes as people are starting to get access to the
hardware in the wild
- new gadget controller driver, cdns2, added
- new typec drivers added
- xhci driver updates
- typec driver updates
- usbip driver fixes
- usb-serial driver updates and fixes
- lots of smaller USB driver updates
All of these have been in linux-next for a while with no reported
problems"

There are situations during the xhci_resume() sequence, which allows for
re-initializing of the XHCI HC. However, in case the HCD is being removed,
these operations may not be needed. Set the removal state before issuing
the runtime PM get on the XHCI device, so that the XHCI resume routine will
know when to bypass the re-init logic.

During XHCI resume, if there was a host controller error detected the
routine will attempt to re-initialize the XHCI HC, so that it can return
back to an operational state. If the XHCI host controller is being
removed, this sequence would be already handled within the XHCI halt path,
leading to a duplicate set of reg ops/calls. In addition, since the XHCI
bus is being removed, the overhead added in restarting the HCD is
unnecessary. Check for the XHC state before setting the reinit_xhc
parameter, which is responsible for triggering the restart.

Add U1/U2 feature support of xHCI for ZHAOXIN.
Since both INTEL and ZHAOXIN need to check the tier where the device is
located to determine whether to enabled U1/U2, remove the previous INTEL
U1/U2 tier policy and add common policy in xhci_check_tier_policy.
If vendor has specific U1/U2 enable policy,quirks can be add to declare.
