If we receive a transfer event indicating that an endpoint should be
halted, but current endpoint state doesn't match it, then the halt might
be just resolved by the stop endpoint completion handler that detects the
halted endpoint due to a context state error.
In this case the TD we halted on is already moved to the cancelled TD list,
and should not be successfully completed and given back anymore.
Let the stop endpoint completion handler reset the endpoint, and then let
the reset endpoint handler give back the cancelled TD among all other
ones on the cancelled TD list

A halted endpoint can be detected both when transfer events complete, and
in stop endpoint command completion. Both these handlers will start
clearing up the halted endpoint and queue a reset endpoint command.
It's possible to get both events for the same halted endpoint if right
after a URB cancel queues a stop endpoint command the endpoint stalls.
Use the EP_HALTED flag to prevent resetting the endpoint twice.

Replace xhci_find_new_dequeue_state() and xhci_queue_new_dequeue_state()
functions with one combined function.
These function were always called after each other, and had a lot of extra
code just to pass the newly found dequeue state from the first function
to the other.
The new function also returns error in case there is a failure to
queue the new dequeue state. This way the caller can decide on
recovery measures to handle it.

Handle race where a stop endpoint command fails with "context state error"
as hardware hasn't actually started the ring yet after a previous urb
cancellation completed and restarted the endpoint.
Flushing the doorbell write that restart the endpoint reduced these cases,
but didn't completely resolve them.
Check if the ring is running in the stop endpoint completion handler, and
issue a new stop endpoint command in this case.

xhci 4.6.9: "A busy endpoint may asynchronously transition from the
Running to the Halted or Error state due to error conditions detected
while processing TRBs. A possible race condition may occur if software,
thinking an endpoint is in the running state, issues a Stop Endpoint
Command, however at the same time the xHC asynchronously transitions
the endpoint to the Halted or Error state. In this case, a Context
State Error may be generated for the command completion. Software
may verify that this case occurred by inspecting the EP State for
Halted or Error when a Stop Endpoint Command results in a Context
State Error."
Halted endpoints were not detected or handled at all in the stop endpoint
completion handler. A set TR Deq ptr command was bluntly queued instead
of resetting the endpoint first. The set TR Deq command would fail with
a context state error.
Fix this case by resetting the halted endpoint first to get it to a
stopped state instead of the halted (error) state.
Handle cancelled TDs once endpoint reset completes,
invalidating cancelled TDs on ring either by turning them to no-op,
or in case ring stopped on cancelled TD then move hardware dequeue pointer
past it, which will clear the cancelled TD from hw cache, and make sure
HW does not process it

Don't queue both a reset endpoint command and a
set TR deq command at once when handling a halted endpoint.
split this into two steps.
Initially only queue a reset endpoint command, and then if needed queue a
set TR deq command in the reset endpoint handler.
Note: This removes the RESET_EP_QUIRK handling which was added in
commit ac9d8fe7c6 ("USB: xhci: Add quirk for Fresco Logic xHCI hardware.")
This quirk was added in 2009 for prototype xHCI hardware meant for
evaluation purposes only, and should not reach consumers.
This hardware could not handle two commands queued at once, and had
bad data in the output context after a reset endpoint command.
After this patch two command are no longer queued at once, so that
part is solved in this rewrite, but the workaround for bad data in the
output context solved by issuing an extra configure endpoint command is
bluntly removed.
Adding this workaround to the new rewrite just adds complexity, and I
think it's time to let this quirk go.
Print a debug message instead.

Stop endpoint command fails with "context state error" if the endpoint is
already stopped.
This case was observed when a previous URB cancel had just completed and
rang the doorbell to restart the ring, when a new URB cancel queued a stop
endpoint command.
>From xHC hardware pov the endpoint had not yet started, so the stop
endpoint command failed with context state error.
Right after this the doorbell ring took effect and ring was restarted.
Interrupt handler saw a stop endpoint command completion event with
"context state error" and discovered that the ring was back up in
running state.
flushing the write reduces these cases in stress testing, but does not
completely remove the issue.

ring buffers shared with the host controller.

Instead of re-reading, masking and endianness correcting the same trb
several times to get the trb type from an event, just do it once and
store it in a local variable.
Also pass the trb_type directly to the vendor specific event handler,
avoiding one more similar read.
In addition to the security benefit this also cleans up the code
and helps readability.

When finishing a TD we walk the endpoint dequeue trb pointer
until it matches the last TRB of the TD.
TDs can contain over 100 TRBs, meaning we call a function 100 times,
do a few comparisons and increase a couple values for each of these calls,
all in interrupt context.
This can all be avoided by adding a pointer to the last TRB segment, and
a number of TRBs in the TD. So instead of walking through each TRB just
set the new dequeue segment, pointer, and number of free TRBs directly.
Getting rid of the while loop also reduces the risk of getting stuck in a
infinite loop in the interrupt handler. Loop relied on valid matching
dequeue and last_trb values to break.

xhci driver links together segments in a ring buffer by turning the last
TRB of a segment into a link TRB, pointing to the beginning of
the next segment.
If the first TRB of every segment for some unknown reason is a link TRB
pointing to the next segment, then prepare_ring() loops indefinitely.
This isn't something the xhci driver would do.
xHC hardware has access to these rings, it sholdn't be writing link
TRBs either, but with broken xHC hardware this could in theory be
possible.

When handling transfer events the event is passed along the handling
callpath and parsed again in several occasions.
The event contains slot_id and endpoint index, from which the driver
endpoint structure can be found. There wasn't however a way to get the
endpoint index or parent usb device from this endpoint structure.
A lot of extra event parsing, and thus some DMA doublefetch cases,
and excess variables and code can be avoided by adding endpoint index
and parent usb virt device pointer to the endpoint structure.

With some USB network adapters, such as DM96xx, the following message
is seen for each maximum size receive packet.
dwc2 ff540000.usb: dwc2_update_urb_state(): trimming xfer length
This happens because the packet size requested by the driver is 1522
bytes, wMaxPacketSize is 64, the dwc2 driver configures the chip to
receive 24*64 = 1536 bytes, and the chip does indeed send more than
1522 bytes of data. Since the event does not indicate an error condition,
the message is just noise. Demote it to debug level.

In some situations, the following error messages are reported.
dwc2 ff540000.usb: dwc2_hc_chhltd_intr_dma: Channel 1 - ChHltd set, but reason is unknown
dwc2 ff540000.usb: hcint 0x00000002, intsts 0x04000021
This is sometimes followed by:
dwc2 ff540000.usb: dwc2_update_urb_state_abn(): trimming xfer length
and then:
WARNING: CPU: 0 PID: 0 at kernel/v4.19/drivers/usb/dwc2/hcd.c:2913
dwc2_assign_and_init_hc+0x98c/0x990
The warning suggests that an odd buffer address is to be used for DMA.
After an error is observed, the receive buffer may be full
(urb->actual_length >= urb->length). However, the urb is still left in
the queue unless three errors were observed in a row. When it is queued
again, the dwc2 hcd code translates this into a 1-block transfer.
If urb->actual_length (ie the total expected receive length) is not
DMA-aligned, the buffer pointer programmed into the chip will be
unaligned. This results in the observed warning.
To solve the problem, abort input transactions after an error with
unknown cause if the entire packet was already received. This may be
a bit drastic, but we don't really know why the transfer was aborted
even though the entire packet was received. Aborting the transfer in
this situation is less risky than accepting a potentially corrupted
packet.
With this patch in place, the 'ChHltd set' and 'trimming xfer length'
messages are still observed, but there are no more transfer attempts
with odd buffer addresses.

The DWC2 documentation states that transfers with zero data length should
set the number of packets to 1 and the transfer length to 0. This is not
currently the case for inbound transfers: the transfer length is set to
the maximum packet length. This can have adverse effects if the chip
actually does transfer data as it is programmed to do. Follow chip
documentation and keep the transfer length set to 0 in that situation.

Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so.
c67x00_do_work() will now run in process context and have further
concurrency (tasklets being serialized among themselves), but this
is done holding the c67x00->lock, so it should be fine. Furthermore,
this patch fixes the usage of the lock in the callback as otherwise
it would need to be irq-safe.
