This is a hardware random number generator. The driver provides both a
/dev/chaoskeyX entry and hooks the entropy source up to the kernel
hwrng interface. More information about the device can be found at
http://chaoskey.org

The USB ID for ChaosKey was allocated from the OpenMoko USB vendor
space and is visible as 'USBtrng' here:

http://wiki.openmoko.org/wiki/USB_Product_IDs

v2: Respond to review from Oliver Neukum &lt;oneukum@suse.de&gt;

 * Delete extensive debug infrastructure and replace it with calls to
   dev_dbg.

 * Allocate I/O buffer separately from device structure to obey
   requirements for non-coherant architectures.

 * Initialize mutexes before registering device to ensure that open
   cannot be invoked before the device is ready to proceed.

 * Return number of bytes read instead of -EINTR when partial read
   operation is aborted due to a signal.

 * Make sure device mutex is unlocked in read error paths.

 * Add MAINTAINERS entry for the driver

<title>USB: Add LVS Test device driver</title>

OTG3 and EH Compliance Plan 1.0 talks about Super Speed OTG Verification
system (SS-OVS) which consists of an excersizer and analyzer.

USB Compliance Suite from Lecroy or Ellisys can act as such SS-OVS for
Link Layer Validation (LVS).

Some modifications are needed for an embedded Linux USB host to pass all
these tests.  Most of these tests require just Link to be in U0. They do
not work with default Linux USB stack since, default stack does port
reset and then starts sending setup packet, which is not expected by
Link Layer Validation (LVS) device of Lecroy Compliance Suit.  Then,
There are many Link Layer Tests which need host to generate specific
traffic.

This patch supports specific traffic generation cases. As of now all the
host Lecroy Link Layer-USBIF tests (except TD7.26) passes
with this patch for single run using  Lecroy USB Compliance Suite
Version 1.98 Build 239 and Lecroy USB Protocol Analyzer version 4.80
Build 1603. Therefore patch seems to be a good candidate for inclusion.
Further modification can be done on top of it.

lvstest driver will not bind to any device by default. It can bind
manually to a super speed USB host controller root hub. Therefore, regular
hub driver must be unbound before this driver is bound. For example, if
2-0:1.0 is the xhci root hub, then execute following to unbind hub driver.

 echo 2-0:1.0 &gt; /sys/bus/usb/drivers/hub/unbind

Then write Linux Foundation's vendor ID which is used by root hubs and
SS root hub's device ID into new_id file. Writing IDs into new_id file
will also bind the lvs driver with any available SS root hub interfaces.

 echo "1D6B 3" &gt; /sys/bus/usb/drivers/lvs/new_id

Now connect LVS device with root hub port.

Test case specific traffic can be generated as follows whenever needed:

1. To issue "Get Device descriptor" command for TD.7.06:
 echo  &gt; /sys/bus/usb/devices/2-0\:1.0/get_dev_desc

2. To set U1 timeout to 127 for TD.7.18
 echo 127 &gt; /sys/bus/usb/devices/2-0\:1.0/u1_timeout

3. To set U2 timeout to 0 for TD.7.18
 echo 0 &gt; /sys/bus/usb/devices/2-0\:1.0/u2_timeout

4. To issue "Hot Reset" for TD.7.29
 echo  &gt; /sys/bus/usb/devices/2-0\:1.0/hot_reset

5. To issue "U3 Entry" for TD.7.35
 echo  &gt; /sys/bus/usb/devices/2-0\:1.0/u3_entry

6. To issue "U3 Exit" for TD.7.36
 echo  &gt; /sys/bus/usb/devices/2-0\:1.0/u3_exit

The Kconfig entries for USB_U132_HCD and USB_FTDI_ELAN default to
(uppercase) "M". But in Kconfig (lowercase) "m" is a magic symbol. "M"
is an ordinary symbol. As "M" is never set these Kconfig symbols will
also not be set by default.

Since I'm not aware of a reason why these driver should be set by
default, let's just drop these lines (that basically do nothing).

An Embedded Host High-Speed Electrical Test (EHSET) test fixture is
used to initiate test modes on a host controller in order to perform
the high speed electrical testing procedure for USB-IF compliance.
When this test fixture is connected to a host, it can enumerate as
one of several selectable VID/PID pairs, each corresponding to one
of the following test modes:

* TEST_SE0_NAK
* TEST_J
* TEST_K
* TEST_PACKET
* HS_HOST_PORT_SUSPEND_RESUME
* SINGLE_STEP_GET_DEV_DESC
* SINGLE_STEP_SET_FEATURE

This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.

This patch adds new driver of SMSC USB3503 USB 2.0 hub controller with HSIC
upstream connectivity and three USB 2.0 downstream ports. The specification
can be found from 'http://www.smsc.com/index.php?tid=295&amp;pid=325'.

The current version have been tested very basic features switching the modes,
HUB-MODE and STANDBY-MODE.
