Arnd Bergmann 8123e4953f usb: ehci: fsl: use bus->sysdev for DMA configuration
For the dual role ehci fsl driver, sysdev will handle the dma
config.

Arnd Bergmann aeb78cda51 usb: chipidea: use bus->sysdev for DMA configuration
Set the dma for chipidea from sysdev. This is inherited from its
parent node. Also, do not set dma mask for child as it is not required
now.

Arnd Bergmann a8c06e407e usb: separate out sysdev pointer from usb_bus
For xhci-hcd platform device, all the DMA parameters are not
configured properly, notably dma ops for dwc3 devices.

The idea here is that you pass in the parent of_node along with
the child device pointer, so it would behave exactly like the
parent already does. The difference is that it also handles all
the other attributes besides the mask.

sysdev will represent the physical device, as seen from firmware
or bus.Splitting the usb_bus->controller field into the
Linux-internal device (used for the sysfs hierarchy, for printks
and for power management) and a new pointer (used for DMA,
DT enumeration and phy lookup) probably covers all that we really
need.

Code analysis shows that intf is set to NULL in usb_disable_device() prior
to setting actconfig to NULL. At the same time, usb_runtime_idle() does not
lock the usb device, and neither does any of the functions in the
traceback. This means that there is no protection against a race condition
where usb_disable_device() is removing dev->actconfig->interface[] pointers
while those are being accessed from autosuspend_check().

To solve the problem, synchronize and validate device state between
autosuspend_check() and usb_disconnect().

kick_hub_wq() is called from hub_activate() even after failures to
communicate with the hub. This results in an endless sequence of
hub event -> hub activate -> wq trigger -> hub event -> ...

Provide two solutions for the problem.

- Only trigger the hub event queue if communication with the hub
  is successful.
- After a suspend failure, only resume already suspended interfaces
  if the communication with the device is still possible.

Each of the changes fixes the observed problem. Use both to improve
robustness.

Gerd Hoffmann 21a60f6e65 ohci-pci: add qemu quirk
On a loaded virtualization host (dozen guests booting at the same time)
it may happen that the ohci controller emulation doesn't manage to do
timely frame processing, with the result that the io watchdog fires and
considers the controller being dead, even though it's only the emulation
being unusual slow due to the load peak.

So, add a quirk for qemu and don't use the watchdog in case we figure we
are running on emulated ohci.  The virtual ohci controller masquerades
as apple ohci controller, but we can identify it by subsystem id.

  without hlock, need to program BAWR/BARD/AHBBRST fields in the sbuscfg
  register to guarantee the AHB master's burst would not overrun or
  underrun the FIFO.

- the sbuscfg register has to be set after the usb controller reset,
  otherwise the value would be overridden to 0. In order to do this, the
  reset callback is registered.

Here is a number of different USB fixes for 4.11-rc2.  Seems like there
 were a lot of unresolved issues that people have been finding for this
 subsystem, and a bunch of good security auditing happening as well from
 Johan Hovold.  There's the usual batch of gadget driver fixes and xhci

 All of these have been in linux-next with no reported issues.

Guenter Roeck dcc7620cad usb: host: xhci-plat: Fix timeout on removal of hot pluggable xhci controllers
Upstream commit 98d74f9cea ("xhci: fix 10 second timeout on removal of
PCI hotpluggable xhci controllers") fixes a problem with hot pluggable PCI
xhci controllers which can result in excessive timeouts, to the point where
the system reports a deadlock.

The same problem is seen with hot pluggable xhci controllers using the
xhci-plat driver, such as the driver used for Type-C ports on rk3399.
Similar to hot-pluggable PCI controllers, the driver for this chip
removes the xhci controller from the system when the Type-C cable is
disconnected.

The solution for PCI devices works just as well for non-PCI devices
and avoids the problem.

A recent change claimed to fix an off-by-one error in the OOB-port
completion handler, but instead introduced such an error. This could
specifically led to modem-status changes going unnoticed, effectively
breaking TIOCMGET.

Note that the offending commit fixes a loop-condition underflow and is
marked for stable, but should not be backported without this fix.

Javier Martinez Canillas fd567653bd usb: phy: isp1301: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

In patch 2e2aa1bc7eff90ecm, USB suspend and wakeup control requests are
passed to SFR_OHCIICR register. If a processor does not have such a

If no such a SFR register is available, all USB suspend control requests
will now be processed using ohci_hub_control()
(like before patch 2e2aa1bc7eff90ecm.)

Tested on an Atmel AT91SAM9G20 with an on-board TI TUSB2046B hub chip
If the last USB device is unplugged from the USB hub, the hub goes into
