USB: option: add XS Stick W100-2 from 4G Systems

2015-12-09T18:43:00+00:00

commit 638148e20c7f8f6e95017fdc13bce8549a6925e0 upstream.

4gsystems sells two total different LTE-surfsticks under the same name.
..
The newer version of XS Stick W100 is from "omega"
..
Under windows the driver switches to the same ID, and uses MI03\6 for
network and MI01\6 for modem.

Now all important things are there:

There is also ttyUSB0, but it is not usable, at least not for at.

The device works well with qmi and ModemManager-NetworkManager.

USB: serial: option: add support for Novatel MiFi USB620L

2015-12-09T18:42:59+00:00

commit e07af133c3e2716db25e3e1e1d9f10c2088e9c1a upstream.

Also known as Verizon U620L.

The device is modeswitched from 1410:9020 to 1410:9022 by selecting the
4th USB configuration:

 $ sudo usb_modeswitch –v 0x1410 –p 0x9020 –u 4

This configuration provides a ECM interface as well as TTYs ('Enterprise
Mode' according to the U620 Linux integration guide).

usb: musb: core: fix order of arguments to ulpi write callback

2015-12-09T18:42:59+00:00

commit 705e63d2b29c8bbf091119084544d353bda70393 upstream.

There is a bit of a mess in the order of arguments to the ulpi write
callback. There is

	int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val)

in drivers/usb/common/ulpi.c;

	struct usb_phy_io_ops {
		...
		int (*write)(struct usb_phy *x, u32 val, u32 reg);
	}

in include/linux/usb/phy.h.

The callback registered by the musb driver has to comply to the latter,
but up to now had "offset" first which effectively made the function
broken for correct users. So flip the order and while at it also
switch to the parameter names of struct usb_phy_io_ops's write.

usblp: do not set TASK_INTERRUPTIBLE before lock

2015-12-09T18:42:59+00:00

commit 19cd80a214821f4b558560ebd76bfb2c38b4f3d8 upstream.

It is not permitted to set task state before lock. usblp_wwait sets
the state to TASK_INTERRUPTIBLE and calls mutex_lock_interruptible.
Upon return from that function, the state will be TASK_RUNNING again.

This is clearly a bug and a warning is generated with LOCKDEP too:

xhci: Add spurious wakeup quirk for LynxPoint-LP controllers

2015-11-09T20:50:25+00:00

commit fd7cd061adcf5f7503515ba52b6a724642a839c8 upstream.

We received several reports of systems rebooting and powering on
after an attempted shutdown. Testing showed that setting
XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT
quirk allowed the system to shutdown as expected for LynxPoint-LP
xHCI controllers. Set the quirk back.

Note that the quirk was originally introduced for LynxPoint and
LynxPoint-LP just for this same reason. See:

commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell")

It was later limited to only concern HP machines as it caused
regression on some machines, see both bug and commit:

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171
commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP machines")

Later it was discovered that the powering on after shutdown
was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP
machine suffered from spontaneous resume from S3 (which should
not be related to the SPURIOUS_WAKEUP quirk at all). An attempt
to fix this then removed the SPURIOUS_WAKEUP flag usage completely.

commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell")

Current understanding is that LynxPoint-LP (Haswell ULT) machines
need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and
plain Lynxpoint (Haswell) machines may _not_ have the quirk
set otherwise they again will restart.

xhci: handle no ping response error properly

commit 3b4739b8951d650becbcd855d7d6f18ac98a9a85 upstream.

If a host fails to wake up a isochronous SuperSpeed device from U1/U2
in time for a isoch transfer it will generate a "No ping response error"
Host will then move to the next transfer descriptor.

Handle this case in the same way as missed service errors, tag the
current TD as skipped and handle it on the next transfer event.

usb: Add device quirk for Logitech PTZ cameras

2015-10-22T21:39:21+00:00

commit 72194739f54607bbf8cfded159627a2015381557 upstream.

Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.

Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.

usb: Use the USB_SS_MULT() macro to get the burst multiplier.

2015-10-22T21:39:21+00:00

commit ff30cbc8da425754e8ab96904db1d295bd034f27 upstream.

Bits 1:0 of the bmAttributes are used for the burst multiplier.
The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
into use.

Use the existing USB_SS_MULT() macro instead to make sure the mult value
and hence max packet calculations are correct for USB3.1 devices.

Note that burst multiplier in bmAttributes is zero based and that
the USB_SS_MULT() macro adds one.
