This reverts commit 6ccb83d6c4.
Commit 6ccb83d6c4 ("usb: xhci: Implement xhci_handshake_check_state()
helper") was introduced to workaround watchdog timeout issues on some
platforms, allowing xhci_reset() to bail out early without waiting
for the reset to complete.
Skipping the xhci handshake during a reset is a dangerous move. The
xhci specification explicitly states that certain registers cannot
be accessed during reset in section 5.4.1 USB Command Register (USBCMD),
Host Controller Reset (HCRST) field:
"This bit is cleared to '0' by the Host Controller when the reset
process is complete. Software cannot terminate the reset process
early by writinga '0' to this bit and shall not write any xHC
Operational or Runtime registers until while HCRST is '1'."
This behavior causes a regression on SNPS DWC3 USB controller with
dual-role capability. When the DWC3 controller exits host mode and
removes xhci while a reset is still in progress, and then tries to
configure its hardware for device mode, the ongoing reset leads to
register access issues; specifically, all register reads returns 0.
These issues extend beyond the xhci register space (which is expected
during a reset) and affect the entire DWC3 IP block, causing the DWC3
device mode to malfunction.

xhci_reset() currently returns -ENODEV if XHCI_STATE_REMOVING is
set, without completing the xhci handshake, unless the reset completes
exceptionally quickly. This behavior causes a regression on Synopsys
DWC3 USB controllers with dual-role capabilities.
Specifically, when a DWC3 controller exits host mode and removes xhci
while a reset is still in progress, and then attempts to configure its
hardware for device mode, the ongoing, incomplete reset leads to
critical register access issues. All register reads return zero, not
just within the xHCI register space (which might be expected during a
reset), but across the entire DWC3 IP block.
This patch addresses the issue by preventing xhci_reset() from being
called in xhci_resume() and bailing out early in the reinit flow when
XHCI_STATE_REMOVING is set.

commit cbc889ab0122366f6cdbe3c28d477c683ebcebc2 upstream.
During the High-Speed Isochronous Audio transfers, xHCI
controller on certain AMD platforms experiences momentary data
loss. This results in Missed Service Errors (MSE) being
generated by the xHCI.
The root cause of the MSE is attributed to the ISOC OUT endpoint
being omitted from scheduling. This can happen when an IN
endpoint with a 64ms service interval either is pre-scheduled
prior to the ISOC OUT endpoint or the interval of the ISOC OUT
endpoint is shorter than that of the IN endpoint. Consequently,
the OUT service is neglected when an IN endpoint with a service
interval exceeding 32ms is scheduled concurrently (every 64ms in
this scenario).
This issue is particularly seen on certain older AMD platforms.
To mitigate this problem, it is recommended to adjust the service
interval of the IN endpoint to not exceed 32ms (interval 8). This
adjustment ensures that the OUT endpoint will not be bypassed,
even if a smaller interval value is utilized.

reset), but across the entire DWC3 IP block.
This patch addresses the issue by preventing xhci_reset() from being
called in xhci_resume() and bailing out early in the reinit flow when
XHCI_STATE_REMOVING is set.

This reverts commit 1c17190880 which is
commit 68c1f1671650b49bbd26e6a65ddcf33f2565efa3 upstream.
It breaks the Android kernel abi and can be brought back in the future
in an abi-safe way if it is really needed.

[ Upstream commit 68c1f1671650b49bbd26e6a65ddcf33f2565efa3 ]
The current xHCI driver does not validate whether a page size of 4096
bytes is supported. Address the issue by setting the page size to the
value supported by the xHCI controller, as read from the Page Size
register. In the event of an unexpected value; default to a 4K page size.
Additionally, this commit removes unnecessary debug messages and instead
prints the supported and used page size once.
The xHCI controller supports page sizes of (2^{(n+12)}) bytes, where 'n'
is the Page Size Bit. Only one page size is supported, with a maximum
page size of 128 KB.

[ Upstream commit dfc88357b6b6356dadea06b2c0bc8041f5e11720 ]
When the device stalls an endpoint, current TD is assigned -EPIPE
status and Reset Endpoint is queued. If a Stop Endpoint is pending
at the time, it will run before Reset Endpoint and fail due to the
stall. Its handler will change TD's status to -EPROTO before Reset
Endpoint handler runs and initiates giveback.
Check if the stall has already been handled and don't try to do it
again. Since xhci_handle_halted_endpoint() performs this check too,
not overwriting td->status is the only difference.
I haven't seen this case yet, but I have seen a related one where
the xHC has already executed Reset Endpoint, EP Context state is
now Stopped and EP_HALTED is set. If the xHC took a bit longer to
execute Reset Endpoint, said case would become this one.

[ Upstream commit cab63934c33b12c0d1e9f4da7450928057f2c142 ]
Event polling delay is set to 0 if there are any pending requests in
either rx or tx requests lists. Checking for pending requests does
not work well for "IN" transfers as the tty driver always queues
requests to the list and TRBs to the ring, preparing to receive data
from the host.
This causes unnecessary busylooping and cpu hogging.
Only set the event polling delay to 0 if there are pending tx "write"
transfers, or if it was less than 10ms since last active data transfer
in any direction.

commit 732f35cf8bdfece582f6e4a9c659119036577308 upstream.
When a USB device is connected to the OTG port, the tegra_xhci_id_work()
routine transitions the PHY to host mode and calls xhci_hub_control()
with the SetPortFeature command to enable port power.
In certain cases, the XHCI controller may be in a low-power state
when this operation occurs. If xhci_hub_control() is invoked while
the controller is suspended, the PORTSC register may return 0xFFFFFFFF,
indicating a read failure. This causes xhci_hc_died() to be triggered,
leading to host controller shutdown.
Example backtrace:
[ 105.445736] Workqueue: events tegra_xhci_id_work
[ 105.445747] dump_backtrace+0x0/0x1e8
[ 105.445759] xhci_hc_died.part.48+0x40/0x270

[ 105.445774] tegra_xhci_id_work+0x130/0x240
To prevent this, ensure the controller is fully resumed before
interacting with hardware registers by calling pm_runtime_get_sync()
prior to the host mode transition and xhci_hub_control().

commit a5c7973539b010874a37a0e846e62ac6f00553ba upstream.
Device tree bindings state that the clock is optional for UHCI platform
controllers, and some existing device trees don't provide those - such
as those for VIA/WonderMedia devices.
The driver however fails to probe now if no clock is provided, because
devm_clk_get returns an error pointer in such case.
Switch to devm_clk_get_optional instead, so that it could probe again
on those platforms where no clocks are given.

commit 9e3a28793d2fde7a709e814d2504652eaba6ae98 upstream.
A Short Packet event before the last TRB of a TD is followed by another
event on the final TRB on spec-compliant HCs, which is most of them.
A 'last_td_was_short' flag was added to know if a TD has just completed
as Short Packet and another event is to come. The flag was cleared after
seeing the event (unless no TDs are pending, but that's a separate bug)
or seeing a new TD complete as something other than Short Packet.
A rework replaced the flag with an 'old_trb_comp_code' variable. When
an event doesn't match the pending TD and the previous event was Short
Packet, the new event is silently ignored.
To preserve old behavior, 'old_trb_comp_code' should be cleared at this
point, but instead it is being set to current comp code, which is often
Short Packet again. This can cause more events to be silently ignored,
even though they are no longer connected with the old TD that completed
short and indicate a serious problem with the driver or the xHC.
Common device classes like UAC in async mode, UVC, serial or the UAS
status pipe complete as Short Packet routinely and could be affected.
Clear 'old_trb_comp_code' to zero, which is an invalid completion code
and the same value the variable starts with. This restores original
behavior on Short Packet and also works for illegal Etron events, which
the code has been extended to cover too.

[ Upstream commit b331a3d8097fad4e541d212684192f21fedbd6e5 ]
Unplugging a USB3.0 webcam from Etron hosts while streaming results
in errors like this:
[ 2.646387] xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 18 comp_code 13

Etron xHC generates two transfer events for the TRB if an error is
detected while processing the last TRB of an isoc TD.
The first event can be any sort of error (like USB Transaction or
Babble Detected, etc), and the final event is Success.
The xHCI driver will handle the TD after the first event and remove it
from its internal list, and then print an "Transfer event TRB DMA ptr
not part of current TD" error message after the final event.
Commit 5372c65e13 ("xhci: process isoc TD properly when there was a
transaction error mid TD.") is designed to address isoc transaction
errors, but unfortunately it doesn't account for this scenario.
This issue is similar to the XHCI_SPURIOUS_SUCCESS case where a success
event follows a 'short transfer' event, but the TD the event points to
is already given back.
Expand the spurious success 'short transfer' event handling to cover
the spurious success after error on Etron hosts.
Kuangyi Chiang reported this issue and submitted a different solution
based on using error_mid_td. This commit message is mostly taken
from that patch.

[ Upstream commit 906dec15b9b321b546fd31a3c99ffc13724c7af4 ]
The TRB pointer of these events points at enqueue at the time of error
occurrence on xHCI 1.1+ HCs or it's NULL on older ones. By the time we
are handling the event, a new TD may be queued at this ring position.
I can trigger this race by rising interrupt moderation to increase IRQ
handling delay. Similar delay may occur naturally due to system load.
If this ever happens after a Missed Service Error, missed TDs will be
skipped and the new TD processed as if it matched the event. It could
be given back prematurely, risking data loss or buffer UAF by the xHC.
Don't complete TDs on xrun events and don't warn if queued TDs don't
match the event's TRB pointer, which can be NULL or a link/no-op TRB.
Don't warn if there are no queued TDs at all.
Now that it's safe, also handle xrun events if the skip flag is clear.
This ensures completion of any TD stuck in 'error mid TD' state right
before the xrun event, which could happen if a driver submits a finite
number of URBs to a buggy HC and then an error occurs on the last TD.

commit bcb60d438547355b8f9ad48645909139b64d3482 upstream.
The OHCI controller (rev 0x02) under LS7A PCI host has a hardware flaw.
MMIO register with offset 0x60/0x64 is treated as legacy PS2-compatible
keyboard/mouse interface, which confuse the OHCI controller. Since OHCI
only use a 4KB BAR resource indeed, the LS7A OHCI controller's 32KB BAR
is wrapped around (the second 4KB BAR space is the same as the first 4KB
internally). So we can add an 4KB offset (0x1000) to the OHCI registers
(from the PCI BAR resource) as a quirk.

commit 1ea050da5562af9b930d17cbbe9632d30f5df43a upstream.
This check is performed before prepare_transfer() and prepare_ring(), so
enqueue can already point at the final link TRB of a segment. And indeed
it will, some 0.4% of times this code is called.
Then enqueue + 1 is an invalid pointer. It will crash the kernel right
away or load some junk which may look like a link TRB and cause the real
link TRB to be replaced with a NOOP. This wouldn't end well.
Use a functionally equivalent test which doesn't dereference the pointer
and always gives correct result.
Something has crashed my machine twice in recent days while playing with
an Etron HC, and a control transfer stress test ran for confirmation has
just crashed it again. The same test passes with this patch applied.

commit bea5892d0ed274e03655223d1977cf59f9aff2f2 upstream.
Current xhci bus resume implementation prevents xHC host from generating
interrupts during high-speed USB 2 and super-speed USB 3 bus resume.
Only reason to disable interrupts during bus resume would be to prevent
the interrupt handler from interfering with the resume process of USB 2
ports.
Host initiated resume of USB 2 ports is done in two stages.
The xhci driver first transitions the port from 'U3' to 'Resume' state,
then wait in Resume for 20ms, and finally moves port to U0 state.
xhci driver can't prevent interrupts by keeping the xhci spinlock
due to this 20ms sleep.
Limit interrupt disabling to the USB 2 port resume case only.
resuming USB 2 ports in bus resume is only done in special cases where
USB 2 ports had to be forced to suspend during bus suspend.
The current way of preventing interrupts by clearing the 'Interrupt
Enable' (INTE) bit in USBCMD register won't prevent the Interrupter
registers 'Interrupt Pending' (IP), 'Event Handler Busy' (EHB) and
USBSTS register Event Interrupt (EINT) bits from being set.
New interrupts can't be issued before those bits are properly clered.
Disable interrupts by clearing the interrupter register 'Interrupt
Enable' (IE) bit instead. This way IP, EHB and INTE won't be set
before IE is enabled again and a new interrupt is triggered.

Queue event polling work with 0 delay in case there are pending transfers
queued up. This is part 2 of a 3 part series that roughly triples dbc
performace when using adb push and pull over dbc.
Max/min push rate after patches is 210/118 MB/s, pull rate 171/133 MB/s,
tested with large files (300MB-9GB) by Łukasz Bartosik
First performance improvement patch was commit 31128e7492
("xhci: dbc: add dbgtty request to end of list once it completes")

Introduce XHCI sideband, which manages the USB endpoints being requested by
a client driver. This is used for when client drivers are attempting to
offload USB endpoints to another entity for handling USB transfers. XHCI
sec intr will allow for drivers to fetch the required information about the
transfer ring, so the user can submit transfers independently. Expose the
required APIs for drivers to register and request for a USB endpoint and to
manage XHCI secondary interrupters.
Driver renaming, multiple ring segment page linking, proper endpoint clean
up, and allowing module compilation added by Wesley Cheng to complete
original concept code by Mathias Nyman.

Upstream resolved the conflict of xhci_process_cancelled_tds() and
xhci_stop_endpoint_sync() declarations in a different order and this
causes merge conflicts when backporting more patches. Align with the
declaration order that upstream has.
