commit f3dccdaade upstream.
The AMD PLL USB quirk is incorrectly enabled on newer Ryzen
chipsets. The logic in usb_amd_find_chipset_info currently checks
for unaffected chipsets rather than affected ones. This broke
once a new chipset was added in e788787ef. It makes more sense
to reverse the logic so it won't need to be updated as new
chipsets are added. Note that the core of the workaround in
usb_amd_quirk_pll does correctly check the chipset.

In some cases the "Allocate & copy" block in ffs_epfile_io() is not

problems when ffs_free_buffer() is called at the end of ffs_epfile_io().
This patch uses kzalloc() instead of kmalloc() in the aio case and memset()
in non-aio case to properly initialize struct ffs_io_data.

[ Upstream commit 5617592927 ]
If the device rejects the control transfer to enable device-initiated
U1/U2 entry, then the device will not initiate U1/U2 transition. To
improve the performance, the downstream port should not initate
transition to U1/U2 to avoid the delay from the device link command
response (no packet can be transmitted while waiting for a response from
the device). If the device has some quirks and does not implement U1/U2,
it may reject all the link state change requests, and the downstream
port may resend and flood the bus with more requests. This will affect
the device performance even further. This patch disables the
hub-initated U1/U2 if the device-initiated U1/U2 entry fails.

commit e244c4699f upstream.
With Link Power Management (LPM) enabled USB3 links transition to low
power U1/U2 link states from U0 state automatically.
Current hub code detects USB3 remote wakeups by checking if the software
state still shows suspended, but the link has transitioned from suspended
U3 to enabled U0 state.
As it takes some time before the hub thread reads the port link state
after a USB3 wake notification, the link may have transitioned from U0
to U1/U2, and wake is not detected by hub code.
Fix this by handling U1/U2 states in the same way as U0 in USB3 wakeup
handling
This patch should be added to stable kernels since 4.13 where LPM was
kept enabled during suspend/resume

commit b2357839c5 upstream.
The old commit 6e4b74e469 ("usb: renesas: fix scheduling in atomic
context bug") fixed an atomic issue by using workqueue for the shdmac
dmaengine driver. However, this has a potential race condition issue
between the work pending and usbhsg_ep_free_request() in gadget mode.
When usbhsg_ep_free_request() is called while pending the queue,
since the work_struct will be freed and then the work handler is
called, kernel panic happens on process_one_work().
To fix the issue, if we could call cancel_work_sync() at somewhere
before the free request, it could be easy. However,
the usbhsg_ep_free_request() is called on atomic (e.g. f_ncm driver
calls free request via gether_disconnect()).
For now, almost all users are having "USB-DMAC" and the DMAengine
driver can be used on atomic. So, this patch adds a workaround for
a race condition to call the DMAengine APIs without the workqueue.
This means we still have TODO on shdmac environment (SH7724), but
since it doesn't have SMP, the race condition might not happen.

Use a 10000us AHB idle timeout in dwc2_core_reset() and make it

This fixes a problem for me where dwc2 would not want to initialize when
updating to 4.19 on a MIPS Lantiq VRX200 SoC. dwc2 worked fine with
4.14.
Testing on my board shows that it takes 180us until AHB master IDLE
state is signalled. The very old vendor driver for this SoC (ifxhcd)
used a 1 second timeout.
Use the same timeout that is used everywhere when polling for
GRSTCTL_AHBIDLE instead of using a timeout that "works for one board"
(180us in my case) to have consistent behavior across the dwc2 driver.

commit bd6742249b upstream
OUT endpoint requests may somtimes have this flag set when
preparing to be submitted to HW indicating that there is an
additional TRB chained to the request for alignment purposes.
If that request is removed before the controller can execute the
transfer (e.g. ep_dequeue/ep_disable), the request will not go
through the dwc3_gadget_ep_cleanup_completed_request() handler
and will not have its needs_extra_trb flag cleared when
dwc3_gadget_giveback() is called. This same request could be
later requeued for a new transfer that does not require an
extra TRB and if it is successfully completed, the cleanup
and TRB reclamation will incorrectly process the additional TRB
which belongs to the next request, and incorrectly advances the
TRB dequeue pointer, thereby messing up calculation of the next
requeust's actual/remaining count when it completes.
The right thing to do here is to ensure that the flag is cleared
before it is given back to the function driver. A good place
to do that is in dwc3_gadget_del_and_unmap_request().

commit b8c3b71808 upstream.
A USB3 device needs to be reset and re-enumarated if the port it
connects to goes to a error state, with link state inactive.
There is no use in trying to recover failed transactions by resetting
endpoints at this stage. Tests show that in rare cases, after multiple
endpoint resets of a roothub port the whole host controller might stop
completely.
Several retries to recover from transaction error can happen as
it can take a long time before the hub thread discovers the USB3
port error and inactive link.
We can't reliably detect the port error from slot or endpoint context
due to a limitation in xhci, see xhci specs section 4.8.3:
"There are several cases where the EP State field in the Output
Endpoint Context may not reflect the current state of an endpoint"
and
"Software should maintain an accurate value for EP State, by tracking it
with an internal variable that is driven by Events and Doorbell accesses"
Same appears to be true for slot state.
set a flag to the corresponding slot if a USB3 roothub port link goes
inactive to prevent both queueing new URBs and resetting endpoints.

USB 3.2 capability in a host can be detected from the

If major is 0x3 and minor 0x20 then the host is USB 3.2 capable.
For USB 3.2 capable hosts set the root hub lane count to 2.
The Major Revision and Minor Revision fields contain a BCD version number.
The value of the Major Revision field is JJh and the value of the Minor
Revision field is MNh for version JJ.M.N, where JJ = major revision number,
M - minor version number, N = sub-minor version number,
e.g. version 3.1 is represented with a value of 0310h.

commit c19dffc0a9 upstream.
An endpoint conflict occurs when the USB is working in device mode
during an isochronous communication. When the endpointA IN direction
is an isochronous IN endpoint, and the host sends an IN token to
endpointA on another device, then the OUT transaction may be missed
regardless the OUT endpoint number. Generally, this occurs when the
device is connected to the host through a hub and other devices are
connected to the same hub.
The affected OUT endpoint can be either control, bulk, isochronous, or
an interrupt endpoint. After the OUT endpoint is primed, if an IN token
to the same endpoint number on another device is received, then the OUT
endpoint may be unprimed (cannot be detected by software), which causes
this endpoint to no longer respond to the host OUT token, and thus, no
corresponding interrupt occurs.
There is no good workaround for this issue, the only thing the software
could do is numbering isochronous IN from the highest endpoint since we
have observed most of device number endpoint from the lowest.

commit babd183915 upstream.
In commit abb621844f ("usb: ch9: make usb_endpoint_maxp() return
only packet size") the API to usb_endpoint_maxp() changed. It used to
just return wMaxPacketSize but after that commit it returned
wMaxPacketSize with the high bits (the multiplier) masked off. If you
wanted to get the multiplier it was now up to your code to call the
new usb_endpoint_maxp_mult() which was introduced in
commit 541b6fe630 ("usb: add helper to extract bits 12:11 of
wMaxPacketSize").
Prior to the API change most host drivers were updated, but no update
was made to dwc2. Presumably it was assumed that dwc2 was too
simplistic to use the multiplier and thus just didn't support a
certain class of USB devices. However, it turns out that dwc2 did use
the multiplier and many devices using it were working quite nicely.
That means that many USB devices have been broken since the API
change. One such device is a Logitech HD Pro Webcam C920.
Specifically, though dwc2 didn't directly call usb_endpoint_maxp(), it
did call usb_maxpacket() which in turn called usb_endpoint_maxp().
Let's update dwc2 to work properly with the new API.

This change fixes a data corruption issue occurred on USB hard disk for
the case that bounce buffer is used during transferring data.
While updating data between sg list and bounce buffer, current
implementation passes mapped sg number (urb->num_mapped_sgs) to
sg_pcopy_from_buffer() and sg_pcopy_to_buffer(). This causes data
not get copied if target buffer is located in the elements after
mapped sg elements. This change passes sg number for full list to
fix issue.
Besides, for copying data from bounce buffer, calling dma_unmap_single()
on the bounce buffer before copying data to sg list can avoid cache issue.
