Sanjeev Sharma ab945eff83 uas: replace WARN_ON_ONCE() with lockdep_assert_held()
on some architecture spin_is_locked() always return false in
uniprocessor configuration and therefore it would be advise
to replace with lockdep_assert_held().

Peter Chen 27c62c2da1 usb: chipidea: otg initialization is only needed when the gadget is supported
We have only needed to enable otg initialization when both of
below conditions are satisfied:

- The controller is otg capable
- The gadget function is enabled

If the controller is otg capable, but is host-only configuration, we do
not need to access register otgsc and do any otg operations (eg, create
otg workqueue).

Peter Chen 026f3fcbb0 usb: core: TPL should apply for both OTG and EH
According to On-The-Go and Embedded Host Supplement to the USB Revision
2.0 Specification, the targeted hosts (non-PC hosts) include both
embedded hosts and otg, and each targeted host product defines the
set of supported peripherals on a TPL (Targeted Peripheral List). So,
TPL should apply for both OTG and embedded host, and the otg support is
not a must for embedded host.

The TPL support feature will only be effect when CONFIG_USB_OTG_WHITELIST
has been chosen and hcd->tpl_support flag is set, it can avoid the enumeration
fails problem for the user who chooses CONFIG_USB_OTG_WHITELIST wrongly.

Johan Hovold c68929f75d USB: quirks: enable device-qualifier quirk for Elan Touchscreen
Enable device-qualifier quirk for Elan Touchscreen, which often fails to
handle requests for the device_descriptor.

Note that the device sometimes do respond properly with a Request Error
(three times as USB core retries), but usually fails to respond at all.
When this happens any further descriptor requests also fails, for
example:

[ 1528.688934] usb 2-7: new full-speed USB device number 4 using xhci_hcd
[ 1530.945588] usb 2-7: unable to read config index 0 descriptor/start: -71
[ 1530.945592] usb 2-7: can't read configurations, error -71

This has been observed repeating for over a minute before eventual
successful enumeration.

That commit causes more problem than fixes. Firstly, kfree()

things are, we will try to dequeue a request that has already

Paul Zimmerman 5dce95554a usb: dwc2: handle DMA buffer unmapping sanely
The driver's handling of DMA buffers for non-aligned transfers
was kind of nuts. For IN transfers, it left the URB DMA buffer
mapped until the transfer completed, then synced it, copied the
data from the bounce buffer, then synced it again.

Instead of that, just call usb_hcd_unmap_urb_for_dma() to unmap
the buffer before starting the transfer. Then no syncing is
required when doing the copy. This should also allow handling of
other types of mappings besides just dma_map_single() ones.

Also reduce the size of the bounce buffer allocation for Isoc
endpoints to 3K, since that's the largest possible transfer size.

Tested on Raspberry Pi and Altera SOCFPGA.

Clip max_transfer_size to 65535 for host. dwc2_hc_setup_align_buf()
allocates coherent buffers with this size, and if it's too large we
can exhaust the coherent DMA pool.

Robert Baldyga b203d0a2e3 usb: dwc2/gadget: assign TX FIFO dynamically
Because we have not enough memory to have each TX FIFO of size at least
3072 bytes (the maximum single packet size with 3 transactions per
microframe), we create four FIFOs of lenght 1024, and four of length
3072 bytes, and assing them to endpoints dynamically according to
maxpacket size value of given endpoint.

Up to now there were initialized 16 TX FIFOs, but we use only 8 IN
endpoints, so we can split available memory for 8 FIFOs to have more
memory for each one.

It needed to do some small modifications in few places in code, because
there was assumption that TX FIFO numbers assigned to endpoints are the
same as the endpoint numbers, which is not true since we have dynamic
FIFO assigning.

Greg Kroah-Hartman 922b83b4aa First round of IIO fixes for the 3.17 cycle.
* Fix an overwritten error return that can prevent deferred probing when
   using of_iio_channel_get_by_name
 * A series that deals with an incorrect reference count when the default
   trigger is set within the main probe routine for a driver.  Can result
   in a double free if the trigger is changed.
 * Fix a buglet with xilinx-xadc concerning setup of the address for an
   aux channel.
 * At91 adc driver could sometimes get a touchscreen reading rather than
   the intended adc channel.  This is fixed by using the channel data register
   instead.
 * Fix some ST magnetometer gain values that differ in production parts from
   the prerelease ones used for driver development.

Greg Kroah-Hartman 213db49399 usb: changes for v3.18 merge window
Quite big pull request this time. Audio and UVC gadgets
 can now be used with our configfs-based binding. We have
 three PHY drivers being removed because a new one has been
 added using new PHY framework.
 
 Gadget framework got a new ->reset callback preparing for
 some other changes to come on next merge window.
 
 A few new drivers came in as well; among those we have a
 new UDC driver from Xilinx and two new glue layers for
 DWC3 (ST and Qualcomm).
 
 DWC3 also learned about tracepoints which will help debugging
 quite a bit.
 
 Other than that, a big series of non-critical fixes and
 cleanups.
 
 All patches have been on linux-next for quite a bit of time
 and I boot tested these changes on platforms I have access
 to and work with mainline.

Mark c80b4495c6 USB: storage: Add quirks for Entrega/Xircom USB to SCSI converters
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.

The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.

Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.

My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.

This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

Mark b6a3ed6779 USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapter
Hi,

The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.

I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.

Alan Stern 7312b5ddd4 USB: EHCI: unlink QHs even after the controller has stopped
Old code in ehci-hcd tries to expedite disabling endpoints after the
controller has stopped, by destroying the endpoint's associated QH
without first unlinking the QH.  This was necessary back when the
driver wasn't so careful about keeping track of the controller's
state.

But now we are careful about it, and the driver knows that when the
controller isn't running, no unlinking delay is needed.  Furthermore,
skipping the unlink step will trigger a BUG() in qh_destroy() when the
preceding QH is released, because the link pointer will be non-NULL.

Removing the lines that skip the unlinking step and go directly to
QH_STATE_IDLE fixes the problem.
