dde34cc501 usb: gadget: mv_udc: refine the driver structure
This patch do the following things:

1. Add header and Copyright for marvell usb driver.
2. Add mv_usb.h in include/linux/platform_data, make the driver
   fits all the marvell platform using the same ChipIdea usb ip.
3. Some SOC may has mutiple clock sources, so let me define it
   in mv_usb_platform_data and give two helper functions named
   udc_clock_enable/udc_clock_disable to deal with the clocks.
4. Different SOCs will have some difference in PHY initialization,
   so we will remove file mv_udc_phy.c and add two funtions in
   mv_usb_platform_data, let the platform relative driver to realize it.
5. Rewrite probe function according to the modification list above. Find
   it will kernel panic when probe failed. The root cause is as follows:
	When probe failed, the error handle may call device_unregister()
	which in return will call gadget_release.In current code,
	gadget_release have two issues:
		1: the_controller is a NULL pointer.
		2: if we free udc here, then the following code in probe
		   will access NULL pointer.

0f91349b89 usb: gadget: convert all users to the new udc infrastructure
peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
register/unregister to the udc-core.

The udc-core will take the first available gadget driver and attach
function driver which is calling usb_gadget_register_driver(). This is
the same behaviour we have right now.

Only dummy_hcd was tested, the others were compiled tested.

ceb80363b2 USB: net2272: driver for PLX NET2272 USB device controller
This is based on the last release from PLX:
	http://www.plxtech.com/files/products/net2000/software/selectiontool/RE061204-net2272-linux2.6.18.tgz

I've managed to contact them and they've confirmed that this driver was
wholly written by PLX (Seth Levy).  While they have no problem with it
being merged (and they've already licensed it as GPL), they don't have
any interest in doing so themselves as this is an old part for them.

ADI has long had an add-on card which has this part on it, so we've been
keeping it up-to-date out of tree.  But now that PLX has confirmed the
source of the driver, we can can take the next step of cleaning it up and
getting it merged.

So here we are!  I've done quite a large clean up of the driver and
attempted to address all the common issues.  Hopefully in the process,
I haven't broken anything.  While it seems to still work with the board
that I have access to, it is not a PCI variant.  So I have not tested
any of the PCI logic myself (beyond clean compile).  Perhaps someone who
actually has a card and cares can do so.

I'll try to address further feedback, but don't expect miracles.  I'm
not really familiar with the part itself, just the platform glue.

f6c826a900 USB: EHCI Debug Port Device Gadget
This is a patch that implements an USB EHCI Debug Device using the
Gadget API. This patch applies to a 2.6.35-rc3 kernel.

The gadget needs a compliant usb controller that forwards the
USB_DEVICE_DEBUG_MODE feature to its gadget.

The gadget provides two configuration modes, one that only printk() the
received data, and one that exposes a serial device to userland
(/dev/ttyGSxxx).

The gadget has been tested on an IGEPv2 board running a 2.6.35-rc1
kernel. The debug port was fed on the host side by a 2.6.34 kernel.

Intel Langwell USB Device Controller is a High-Speed USB OTG device
controller in Intel Moorestown platform. It can work in OTG device mode
with Intel Langwell USB OTG transceiver driver as well as device-only
mode. The number of programmable endpoints is different through
controller revision.

NOTE:
This patch is the first version Intel Langwell USB OTG device controller
driver. The bug fixing is on going for some hardware and software
issues.  Intel Langwell USB OTG transceiver driver and EHCI driver
patches will be submitted later.

Supported features:
 - USB OTG protocol support with Intel Langwell USB OTG transceiver
   driver (turn on CONFIG_USB_LANGWELL_OTG)
 - Support control, bulk, interrupt and isochronous endpoints
   (isochronous not tested)
 - PCI D0/D3 power management support
 - Link Power Management (LPM) support

Tested gadget drivers:
 - g_file_storage
 - g_ether
 - g_zero

The passed tests:
 - g_file_storage: USBCV Chapter 9 tests
 - g_file_storage: USBCV MSC tests
 - g_file_storage: from/to host files copying
 - g_ether: ping, ftp and scp files from/to host
 - Hotplug, with and without hubs

Known issues:
 - g_ether: failed part of USBCV chap9 tests
 - LPM support not fully tested

TODO:
 - g_ether: pass all USBCV chap9 tests
 - g_zero: pass usbtest tests
 - Stress tests on different gadget drivers

compilation, since it works poorly when key parts are library
code (with init sections etc).  Instead be as close as we can
to "gcc --combine ...".

19e2068015 usb gadget: new "CDC Composite" gadget driver
This is a simple example of a composite gadget, combining two
Communications Class Device (CDC) functions:  ECM and ACM.

This provides a clear example of how the composite gadget framework
is intended to work.  It's surprising that MS-Windows (or at least,
XP and previous) won't "just work" with something this simple...

One /proc/bus/usb/devices listing looks like:

  T:  Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 46 Spd=480 MxCh= 0

  E:  Ad=05(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms

Not all USB peripheral controller hardware can support this driver.
All the highspeed-capable peripheral controllers with drivers now in
the mainline kernel seem to support this, as does omap_udc.  But
many full speed controllers don't have enough endpoints, or (as with
the PXA controllers) don't support altsettings.

Lightly tested.

2b3d942c48 usb ethernet gadget: split out network core
Abstract the peripheral side Ethernet-over-USB link layer code from
the all-in-one Ethernet gadget driver into a component that can be
called by various functions, so the various flavors can be split
apart and selectively reused.

A notable difference from the approach taken with the serial link
layer code (beyond talking to NET not TTY) is that because of the
initialization requirements, this only supports one network link.
(And one set of Ethernet link addresses.)

That is, each configuration may have only one instance of a network
function.  This doesn't change behavior; the current code has that
same restriction.  If you want multiple logical links, that can
easily be done using network layer tools.

4d5a73dc39 usb gadget serial: split out CDC ACM function
Split out CDC ACM parts of "gadget serial" to a "function driver".
Some key structural differences from the previous ACM support, shared
with with the generic serial function (next patch):

 - As a function driver, it can be combined with other functions.
   One gadget configuration could offer both serial and network
   links, as an example.

 - One serial port can be exposed in multiple configurations;
   the /dev/ttyGS0 node could be exposed regardless of which
   config the host selected.

 - One configuration can expose multiple serial ports, such as
   ttyGS0, ttyGS1, ttyGS2, and ttyGS3.

This code should be a lot easier to understand than the previous
all-in-one-big-file version of the driver.

097db1d034 usb gadget zero: use composite gadget framework
Update Gadget Zero to use the more modular versions of the loopback
and source/sink configuration drivers which build on the new gadget
framework code.

The core code is a LOT simpler, and it should be much easier now to
understand how the parts fit together.  The conversion is an overall
source shrink in terms of this gadget, since it uses more midlayer
support.  However, it's an overall increase in object size because
there's less sharing between the two configurations (improves code
clarity) and because the midlayer is a bit more functional than this
driver actually needs.

a7707adf9e usb gadget: use new serial core
Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue,
and remove all the orignal tangled-up code.  Update the documentation
accordingly.  This is a net object code shrink and cleanup; it should
make it a lot easier to see how the TTY glue should accomodate updates
to the TTY layer, be bugfixed, etc.

Notable behavior changes include:  it can now support getty even when
there's no USB connection; it fits properly into the mdev/udev world;
and RX handling is better (throttling works, and low latency).

Configurations with scripts setting up the /dev/ttygserial device node
(with "experimental" major number) may want to change that to be a
symlink pointing to the /dev/ttyGS0 file, as a migration aid; else,
just switch entirely over to mdev/udev.
