Greg Kroah-Hartman c05fecb1d5 USB: serial: add vizzini driver
Here's a driver for the Vizzini USB to serial device.
It looks to be copied from cdc-acm, and probably can be cleaned up a lot
more.  Also, there's some odd "try to grab another interface" that is
probably wrong.  And, if this really is a cdc-acm device, it probably
should just be a quirk of the cdc-acm device, but I can't figure that
out, and people have been using this driver for a long time now.  So
merge it to let people use their hardware and clean it up over time.

Driver written by Rob Duncan but cleaned up and forward ported to the
latest kernel tree by me.

Roland Dreier 9c58b7ddd7 target: Simplify fabric sense data length handling
Every fabric driver has to supply a se_tfo->set_fabric_sense_len()
method, just so iSCSI can return an offset of 2.  However, every fabric
driver is already allocating a sense buffer and passing it into the
target core, either via transport_init_se_cmd() or target_submit_cmd().

So instead of having iSCSI pass the start of its sense buffer into the
core and then later tell the core to skip the first 2 bytes, it seems
easier for iSCSI just to do the offset of 2 when it passes the sense
buffer into the core.  Then we can drop the se_tfo->set_fabric_sense_len()
everywhere, and just add a couple of lines of code to iSCSI to set the
sense data length to the beginning of the buffer right before it sends
it over the network.

(nab: Remove .set_fabric_sense_len usage from tcm_qla2xxx_npiv_ops +
      change transport_get_sense_buffer to follow v3.6-rc6 code w/o
      ->set_fabric_sense_len usage)

Greg Kroah-Hartman f80e866f72 xHCI patches for 3.7
Hi Greg,
 
 Here's seven patches for 3.7.
 
 The first four fix an issue with Set Address command timeouts.  It turns out
 that Set Address timeouts can trigger a warning that was put in to avoid a NULL
 pointer dereference.  This patchset fixes the underlying cause of the NULL
 pointer that was papered over by the warning.  They should be applied to stable,
 but I'm a bit nervous about the size, so I'd rather they go into 3.7, rather
 than trying to stuff them into a late 3.6-rc.
 
 The other three patches are various trivial fixes.

Elric Fu b63f4053cc xHCI: handle command after aborting the command ring
According to xHCI spec section 4.6.1.1 and section 4.6.1.2,
after aborting a command on the command ring, xHC will
generate a command completion event with its completion
code set to Command Ring Stopped at least. If a command is
currently executing at the time of aborting a command, xHC
also generate a command completion event with its completion
code set to Command Abort. When the command ring is stopped,
software may remove, add, or rearrage Command Descriptors.

To cancel a command, software will initialize a command
descriptor for the cancel command, and add it into a
cancel_cmd_list of xhci. When the command ring is stopped,
software will find the command trbs described by command
descriptors in cancel_cmd_list and modify it to No Op
command. If software can't find the matched trbs, we can
think it had been finished.

This patch should be backported to kernels as old as 3.0, that contain
the commit 7ed603ecf8 "xhci: Add an
assertion to check for virt_dev=0 bug." That commit papers over a NULL
pointer dereference, and this patch fixes the underlying issue that
caused the NULL pointer dereference.

Elric Fu b92cc66c04 xHCI: add aborting command ring function
Software have to abort command ring and cancel command
when a command is failed or hang. Otherwise, the command
ring will hang up and can't handle the others. An example
of a command that may hang is the Address Device Command,
because waiting for a SET_ADDRESS request to be acknowledged
by a USB device is outside of the xHC's ability to control.

To cancel a command, software will initialize a command
descriptor for the cancel command, and add it into a
cancel_cmd_list of xhci.

Greg Kroah-Hartman 799ee9243d USB: serial: add zte_ev.c driver
This adds a driver for the zte_ev set of usb to serial devices.  It is
based on a patch floating around the internet that modified the generic
usb-serial driver to only work for this type of device.

I've left comments in the code that I think show the data commands being
sent to the device, which I'm guessing come from a usb analyzer.  Maybe
they can help others out as well.

Many thanks to nirinA raseliarison for pointing the original patch out
to me, and for testing that the driver works properly.

Michael Grzeschik db89960e50 usb: chipidea: udc: don't stall endpoint if request list is empty in isr_tr_complete_low
When attaching an imx28 or imx53 in USB gadget mode to a Windows host and
starting a rndis connection we see this message every 4-10 seconds:

    g_ether gadget: high speed config #2: RNDIS

Analysis shows that each time this message is printed, the rndis connection is
re-establish due to a reset because of a stalled endpoint (ep 0, dir 1). The
endpoint is stalled because the reqeust complete bit on that endpoint is set,
but in isr_tr_complete_low() the endpoint request list (mEp->qh.queue) is
empty.

This patch removed this check, because the code doesn't take the following
situation into account:

The loop over all endpoints in isr_tr_complete_handler() will call ep_nuke() on
both ep0/dir0 and ep/dir1 in the first loop. Pending reqeusts will be flushed
and completed here. There seems to be a race condition, the request is nuked,
but the request complete bit will be set, too. The subsequent check (in
ep0/dir1's loop cycle) for endpoint request list (mEp->qh.queue) empty will
fail.

Both other mainline chipidea drivers (mv_udc_core.c and fsl_udc_core.c) don't
have this check.

children, which are already deallocated. Simple modprobe dummy_hcd &&

in hub_disconnect().

usb: xceiv: patches for v3.7 merge window

nop xceiv got its own header to avoid polluting otg.h. It has also
learned to work as USB2 and USB3 phys so we can use it on USB3
controllers.

Pavankumar Kondeti 3d037774b4 EHCI: Update qTD next pointer in QH overlay region during unlink
There is a possibility of QH overlay region having reference to a stale
qTD pointer during unlink.

Consider an endpoint having two pending qTD before unlink process begins.
The endpoint's QH queue looks like this.

qTD1 --> qTD2 --> Dummy

To unlink qTD2, QH is removed from asynchronous list and Asynchronous
Advance Doorbell is programmed.  The qTD1's next qTD pointer is set to
qTD2'2 next qTD pointer and qTD2 is retired upon controller's doorbell
interrupt.  If QH's current qTD pointer points to qTD1, transfer overlay
region still have reference to qTD2. But qtD2 is just unlinked and freed.
This may cause EHCI system error.  Fix this by updating qTD next pointer
in QH overlay region with the qTD next pointer of the current qTD.

Lan Tianyu ca9c9d0c92 usb : Add sysfs files to control port power.
This patch adds two sysfs files for each usb hub port to allow userspace
to control the port power policy.

For an upcoming Intel xHCI roothub, this will translate into ACPI calls
to completely power off or power on the port.  As a reminder, when these
ports are completely powered off, the USB host and device will see a
physical disconnect.  All future USB device connections will be lost,
and the device will not be able to signal a remote wakeup.

The control sysfs file can be written to with two options:
"on" - port power must be on.
"off" - port must be off.

The state sysfs file reports usb port's power state:
"on" - powered on
"off" - powered off
"error" - can't get power state

For now, let userspace dictate the port power off policy.  Future
patches may add an in-kernel policy.

Alan Stern pointed out that a USB port could potentially get powered off
when the attached USB device is in the middle of enumerating, due to
race conditions:
	http://marc.info/?l=linux-usb&m=134130616707548&w=2

If that happens, we need to ensure the enumeration fails.  If a call to
usb_get_descriptor() fails for a reason other than a Stall, return an
error.  That should handle the case where the port is powered off.

Lan Tianyu f7ac7787ad usb/acpi: Use ACPI methods to power off ports.
Upcoming Intel systems will have an ACPI method to control whether a USB
port can be completely powered off.  The implication of powering off a
USB port is that the device and host sees a physical disconnect, and
subsequent port connections and remote wakeups will be lost.

Add a new function, usb_acpi_power_manageable(), that can be used to
find whether the usb port has ACPI power resources that can be used to
power on and off the port on these machines. Also add a new function
called usb_acpi_set_power_state() that controls the port power via these
ACPI methods.

When the USB core calls into the xHCI hub driver to power off a port,
check whether the port can be completely powered off via this new ACPI
mechanism.  If so, call into these new ACPI methods.  Also use the ACPI
methods when the USB core asks to power on a port.

Lan Tianyu 05f916894a usb/acpi: Store info on device removability.
In the upcoming USB port power off patches, we need to know whether a
USB port can ever see a disconnect event.  Often USB ports are internal
to a system, and users can't disconnect USB devices from that port.
Sometimes those ports will remain empty, because the OEM chose not to
connect an internal USB device to that port.

According to ACPI Spec 9.13, PLD indicates whether USB port is
user visible and _UPC indicates whether a USB device can be connected to
the USB port (we'll call this "connectible").  Here's a matrix of the
possible combinations:

Visible Connectible
		Name		Example
-------------------------------------------------------------------------

Yes	No	Unknown		(Invalid state.)

Yes	Yes	Hot-plug	USB ports on the outside of a laptop.
				A user could freely connect and disconnect
				USB devices.

No	Yes	Hard-wired	A USB modem hard-wired to a port on the
				inside of a laptop.

No	No	Not used	The port is internal to the system and
				will remain empty.

Represent each of these four states with an enum usb_port_connect_type.
The four states are USB_PORT_CONNECT_TYPE_UNKNOWN,
USB_PORT_CONNECT_TYPE_HOT_PLUG, USB_PORT_CONNECT_TYPE_HARD_WIRED, and
USB_PORT_NOT_USED.  When we get the USB port's acpi_handle, store the
state in connect_type in struct usb_port.

Lan Tianyu ff823c79a5 usb: move children to struct usb_port
The usb_device structure contains an array of usb_device "children".
This array is only valid if the usb_device is a hub, so it makes no
sense to store it there.  Instead, store the usb_device child
in its parent usb_port structure.

Since usb_port is an internal USB core structure, add a new function to
get the USB device child, usb_hub_find_child().  Add a new macro,
usb_hub_get_each_child(), to iterate over all the children attached to a
particular USB hub.

Remove the printing the USB children array pointer from the usb-ip
driver, since it's really not necessary.

This patch turns each USB port on a hub into a new struct device.  This
new device has the USB hub interface device as its parent.  The port
devices are stored in a new structure (usb_port), and an array of
usb_ports are dynamically allocated once we know how many ports the USB
hub has.

Move the port_owner variable out of usb_hub and into this new structure.

A new file will be created in the hub interface sysfs directory, so
add documentation.

Hans de Goede 0837e7e527 usbfs: Add a new disconnect-and-claim ioctl (v2)
Apps which deal with devices which also have a kernel driver, need to do
the following:
1) Check which driver is attached, so as to not detach the wrong driver
   (ie detaching usbfs while another instance of the app is using the device)
2) Detach the kernel driver
3) Claim the interface

Where moving from one step to the next for both 1-2 and 2-3 consists of
a (small) race window. So currently such apps are racy and people just live
with it.

This patch adds a new ioctl which makes it possible for apps to do this
in a race free manner. For flexibility apps can choose to:
1) Specify the driver to disconnect
2) Specify to disconnect any driver except for the one named by the app
3) Disconnect any driver

Note that if there is no driver attached, the ioctl will just act like the
regular claim-interface ioctl, this is by design, as returning an error for
this condition would open a new bag of race-conditions.

Changes in v2:
-Fix indentation of if blocks where the condition spans multiple lines

Bjørn Mork f08dea7348 USB: ftdi_sio: do not claim CDC ACM function
The Microchip vid:pid 04d8:000a is used for their CDC ACM
demo firmware application.  This is a device with a single
function conforming to the CDC ACM specification and with
the intention of demonstrating CDC ACM class firmware and
driver interaction.  The demo is used on a number of
development boards, and may also be used unmodified by
vendors using Microchip hardware.

Some vendors have re-used this vid:pid for other types of
firmware, emulating FTDI chips. Attempting to continue to
support such devices without breaking class based
applications that by matching on interface
class/subclass/proto being ff/ff/00.  I have no information
about the actual device or interface descriptors, but this
will at least make the proper CDC ACM devices work again.
Anyone having details of the offending device's descriptors
should update this entry with the details.

Mike Thompson 363366cf61 usb: otg: mxs-phy: Fix mx23 operation
Currently mx23 fails to enumerate a USB device:

[ 1.300000] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1.520000] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1.740000] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1.960000] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 2.180000] hub 1-0:1.0: unable to enumerate USB device on port 1

Use a kernel workqueue to asynchronously delay the setting of
ENHOSTDISCONDETECT bit until after higher level hub connect/reset processing
is complete.  Prematurely setting the bit prevents the connection
processing from completing and not setting it prevents disconnect from being
detected. No delay is needed for clearing of ENHOSTDISCONDETECT.

Successfully tested on mx23-olinuxino (micro, mini and maxi variants) and mx28evk.

Sebastian Andrzej Siewior ed9cbda63d usb: gadget: remove usb_gadget_controller_number()
The bcdDevice field is defined as
|Device release number in binary-coded decimal
in the USB 2.0 specification. We use this field to distinguish the UDCs
from each other. In theory this could be used on the host side to apply
certain quirks if the "special" UDC in combination with this gadget is
used. This hasn't been done as far as I am aware. In practice it would
be better to fix the UDC driver before shipping since a later release
might not need this quirk anymore.

There are some driver in tree (on the host side) which use the bcdDevice
field to figure out special workarounds for a given firmware revision.
This seems to make sense. Therefore this patch converts all gadgets
(except a few) to use the kernel version instead a random 2 or 3 plus
the UDC number. The few that don't report kernel's version are:
- webcam
  This one reports always a version 0x10 so allow it to do so in future.
- nokia
  This one reports always 0x211. The comment says that this gadget works
  only if the UDC supports altsettings so I added a check for this.
- serial
  This one reports 0x2400 + UDC number. Since the gadget version is 2.4
  this could make sense. Therefore bcdDevice is 0x2400 here.

I also remove various gadget_is_<name> macros which are unused. The
remaining few macros should be moved to feature / bug bitfield.

Some gadgets provide custom entry here. Some may override it with an
etntry that is also created by composite if there was no value sumbitted

This patch removes all "custom manufacturer" strings which are the same
as these which are created by composite. Then it moves the creation of
the default manufacturer string to usb_composite_overwrite_options() in
case no command line argument has been used and the entry is still an
empty string.
By doing this we get rid of the global variable "composite_manufacturer"
in composite.

As Felipe pointed out, the function / usage is very dumb actually. This is
used for the following reasons:
- epautoconf ep hint (could provide a per-gadget callback)
- miss-features. currently the missing altsetting on pxa's and something
  ZLP related on musbhdrc (looks like an optimisation which could be

Greg Kroah-Hartman 23649aa6f1 usb: fixes for v3.6-rc4
Here's a rather big set of fixes for v3.6-rc4.
 
 There are some fixes for bugs which have been pending for a long
 time and only now were uncovered, like the musb and dwc3 patches.
 
 We have some remaining fixes for the ep->desc patch series from
 Ido, a fix for renesas DMA usage, IRQ check on musb's DMA and
 an oops fix on musb Host implementation.
 
 All patches have been pending on linux-usb for a long time and
 shouldn't cause any further regressions.

dma_controller_create() in this MUSB DMA driver only regards 0 as a wrong IRQ
number, despite platform_get_irq_byname() that it calls returns -ENXIO in that
case. It leads to calling request_irq() with a negative IRQ number, and when it
naturally fails, the following is printed to the console:

request_irq -6 failed!

and the DMA controller is not created.

Sebastian Andrzej Siewior 1b68a4ca2d usb: gadget: dummy_hcd: fixup error probe path
If USB2 host controller probes fine but USB3 does not then we don't
remove the USB controller properly and lock up the system while the HUB
code will try to enumerate the USB2 controller and access memory which
is no longer available in case the dummy_hcd was compiled as a module.

This is a problem since 448b6eb1 ("USB: Make sure to fetch the BOS desc
for roothubs.) if used in USB3 mode because dummy does not provide this
descriptor and explodes later.

Pratyush Anand 0416e494ce usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced
In case of ep0 out, if length is not aligned to maxpacket size then we use
dwc->ep_bounce_addr for dma transfer and not request->dma. Since, we have
alreday done memcpy from dwc->ep0_bounce to request->buf, so we do not need to
issue cache sync function. In fact, cache sync function will bring wrong data
in request->buf from request->dma in this scenario.

So, cache sync function must not be executed in case of ep0 bounced.
