commit c7721e15f434920145c376e8fe77e1c079fc3726 upstream.
According to the i.MX6UL Errata document:
https://www.nxp.com/docs/en/errata/IMX6ULCE.pdf
ERR007881 also affects i.MX6UL, so pass the
CI_HDRC_DISABLE_DEVICE_STREAMING flag to workaround the issue.

commit a353397b0d5dfa3c99b372505db3378fc919c6c6 upstream.
In many cases a function that supports SuperSpeed can very well
operate in SuperSpeedPlus, if a gadget controller supports it,
as the endpoint descriptors (and companion descriptors) are
generally identical and can be re-used. This is true for two
commonly used functions: Android's ADB and MTP. So we can simply
assign the usb_function's ssp_descriptors array to point to its
ss_descriptors, if available. Similarly, we need to allow an
epfile's ioctl for FUNCTIONFS_ENDPOINT_DESC to correctly
return the corresponding SuperSpeed endpoint descriptor in case
the connected speed is SuperSpeedPlus as well.
The only exception is if a function wants to implement an
Isochronous endpoint capable of transferring more than 48KB per
service interval when operating at greater than USB 3.1 Gen1
speed, in which case it would require an additional SuperSpeedPlus
Isochronous Endpoint Companion descriptor to be returned as part
of the Configuration Descriptor. Support for that would need
to be separately added to the userspace-facing FunctionFS API
which may not be a trivial task--likely a new descriptor format
(v3?) may need to be devised to allow for separate SS and SSP
descriptors to be supplied.

commit a251963f76fa0226d0fdf0c4f989496f18d9ae7f upstream.
Add an interface-number sanity check before testing the device flags to
avoid relying on undefined behaviour when left shifting in case a device
uses an interface number greater than or equal to BITS_PER_LONG (i.e. 64
or 32).

commit 862ee699fefe1e6d6f2c1518395f0b999b8beb15 upstream.
The console part of sisusbvga is broken vs. printk(). It uses in_atomic()
to detect contexts in which it cannot sleep despite the big fat comment in
preempt.h which says: Do not use in_atomic() in driver code.
in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which
means that spin/rw_lock held regions are not detected by it.
There is no way to make this work by handing context information through to
the driver and this only can be solved once the core printk infrastructure
supports sleepable console drivers.
Make it depend on BROKEN for now.

commit c1373f10479b624fb6dba0805d673e860f1b421d upstream.
If a USB2 device wakeup is not enabled/supported the link state may
still be in U0 in xhci_bus_suspend(), where it's then manually put
to suspended U3 state.
Just as with selective suspend the device needs time to enter U3
suspend before continuing with further suspend operations
(e.g. system suspend), otherwise we may enter system suspend with link
state in U0.

This is a partial revert of commit 2bb70f0a4b23 ("USB: serial:
option: support dynamic Quectel USB compositions")
The Quectel BG96 is different from most other modern Quectel modems,
having serial functions with 3 endpoints using ff/ff/ff and ff/fe/ff
class/subclass/protocol. Including it in the change to accommodate
dynamic function mapping was incorrect.
Revert to interface number matching for the BG96, assuming static
layout of the RMNET function on interface 4. This restores support
for the serial functions on interfaces 2 and 3.

It clears trb->length as zero before preparing td, but if scatter
buffer is used for td, there are several trbs within td, it needs to clear
every trb->length as zero, otherwise, the default value for trb->length
may not be zero after it begins to use the second round of trb rings.

Commit 2f964780c03b ("USB: core: replace %p with %pK") used the %pK
format specifier for a bunch of __user pointers. But as the 'K' in
the specifier indicates, it is meant for kernel pointers. The reason
for the %pK specifier is to avoid leaks of kernel addresses, but when
the pointer is to an address in userspace the security implications
are minimal. In particular, no kernel information is leaked.
This patch changes the __user %pK specifiers (used in a bunch of
debugging output lines) to %px, which will always print the actual
address with no mangling. (Notably, there is no printk format
specifier particularly intended for __user pointers.)

Commit 3e4f8e21c4f2 ("USB: core: fix check for duplicate endpoints")
aimed to make the USB stack more reliable by detecting and skipping
over endpoints that are duplicated between interfaces. This caused a
regression for a Hercules audio card (reported as Bugzilla #208357),
which contains such non-compliant duplications. Although the
duplications are harmless, skipping the valid endpoints prevented the
device from working.
This patch fixes the regression by adding ENDPOINT_IGNORE quirks for
the Hercules card, telling the kernel to ignore the invalid duplicate
endpoints and thereby allowing the valid endpoints to be used as
intended.

built-in usb-audio card
Add a USB_QUIRK_DISCONNECT_SUSPEND quirk for the Lenovo TIO built-in
usb-audio. when A630Z going into S3,the system immediately wakeup 7-8
seconds later by usb-audio disconnect interrupt to avoids the issue.
eg dmesg:
....
[ 626.974091 ] usb 7-1.1: USB disconnect, device number 3
....
....
[ 1774.486691] usb 7-1.1: new full-speed USB device number 5 using xhci_hcd

[ 1775.048590] usb 7-1.1: 2:1: cannot get freq at ep 0x1
.......
Seeking a better fix, we've tried a lot of things, including:
- Check that the device's power/wakeup is disabled
- Check that remote wakeup is off at the USB level
- All the quirks in drivers/usb/core/quirks.c
e.g. USB_QUIRK_RESET_RESUME,
USB_QUIRK_RESET,
USB_QUIRK_IGNORE_REMOTE_WAKEUP,
USB_QUIRK_NO_LPM.
but none of that makes any difference.
There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.
Introduce a quirk to disable the port during suspend when the modem is
detected.

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. We should decrease the usage count
whetever it succeeded or failed(maybe runtime of the device has
error, or device is in inaccessible state, or other error state).
If we do not call put operation to decrease the reference, it will
result in reference leak in xhci_histb_probe. Moreover, this
device cannot enter the idle state and always stay busy or other
non-idle state later. So we fixed it by jumping to error handling
branch.
