commit 38317f5c0f2faae5110854f36edad810f841d62f upstream.

This reverts commit ffb80fc672c3a7b6afd0cefcb1524fb99917b2f3.

Turns out that commit is wrong. Host controllers are allowed to use
Clear Feature HALT as means to sync data toggle between host and

commit effd14f66cc1ef6701a19c5a56e39c35f4d395a5 upstream.

Cherry G230 Stream 2.0 (G85-231) and 3.0 (G85-232) need this quirk to
function correctly. This fixes a but where double pressing numlock locks
up the device completely with need to replug the keyboard.

commit 958c0bd86075d4ef1c936998deefe1947e539240 upstream.

Realtek USB3.0 Card Reader [0bda:0328] reports wrong port status on
Cannon lake PCH USB3.1 xHCI [8086:a36d] after resume from S3,
after clear port reset it works fine.

Since this device is registered on USB3 roothub at boot,
when port status reports not superspeed, xhci_get_port_status will call
an uninitialized completion in bus_state[0].
Kernel will hang because of NULL pointer.

Restrict the USB2 resume status check in USB2 roothub to fix hang issue.

commit 11644a7659529730eaf2f166efaabe7c3dc7af8c upstream.

Implement workaround for ThunderX2 Errata-129 (documented in
CN99XX Known Issues" available at Cavium support site).
As per ThunderX2errata-129, USB 2 device may come up as USB 1
if a connection to a USB 1 device is followed by another connection to
a USB 2 device, the link will come up as USB 1 for the USB 2 device.

Resolution: Reset the PHY after the USB 1 device is disconnected.
The PHY reset sequence is done using private registers in XHCI register
space. After the PHY is reset we check for the PLL lock status and retry
the operation if it fails. From our tests, retrying 4 times is sufficient.

Add a new quirk flag XHCI_RESET_PLL_ON_DISCONNECT to invoke the workaround
in handle_xhci_port_status().

commit 36b6857932f380fcb55c31ac75857e3e81dd583a upstream.

We now have 32 different quirks, and the field that holds them
is full. Let's bump it up to the next stage so that we can handle
some more... The type is now an unsigned long long, which is 64bit
on most architectures.

We take this opportunity to change the quirks from using (1 &lt;&lt; x)
to BIT_ULL(x).

<title>usb: xhci: Prevent bus suspend if a port connect change or polling state is detected</title>

commit 2f31a67f01a8beb22cae754c53522cb61a005750 upstream.

USB3 roothub might autosuspend before a plugged USB3 device is detected,
causing USB3 device enumeration failure.

USB3 devices don't show up as connected and enabled until USB3 link trainig
completes. On a fast booting platform with a slow USB3 link training the
link might reach the connected enabled state just as the bus is suspending.

If this device is discovered first time by the xhci_bus_suspend() routine
it will be put to U3 suspended state like the other ports which failed to
suspend earlier.

The hub thread will notice the connect change and resume the bus,
moving the port back to U0

This U0 -&gt; U3 -&gt; U0 transition right after being connected seems to be
too much for some devices, causing them to first go to SS.Inactive state,
and finally end up stuck in a polling state with reset asserted

Fix this by failing the bus suspend if a port has a connect change or is
in a polling state in xhci_bus_suspend().

Don't do any port changes until all ports are checked, buffer all port
changes and only write them in the end if suspend can proceed

commit d9193efba84fe4c4aa22a569fade5e6ca971f8af upstream.

Observed "TRB completion code (27)" error which corresponds to Stopped -
Length Invalid error(xhci spec section 4.17.4) while connecting USB to
SATA bridge.

Looks like this case was not considered when the following patch[1] was
committed. Hence adding this new check which can prevent
the invalid byte size error.

commit 08fd9a82fda86529bb2f2af3c2f7cb657b4d3066 upstream.

If dwc3_core_init_mode() fails with deferred probe,
next probe fails on sysfs with

sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:11.0/dwc3.0.auto/dwc3.0.auto.ulpi'

To avoid this failure, clean up ULPI device.
