fa06920a3e usb: gadget: Remove File-backed Storage Gadget (g_file_storage).
The File-backed Storage Gadget (g_file_storage) gadget has been replaced
with Mass Storage Gadget (g_mass_storage) which uses the composite
framework.  This commit removes g_file_storage (and most references to it).

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.

3b4a3fc0ba usb: gadget: move usb_gadget_controller_number() into a .c file and libcomposite
After I moved the function from the header file to the c file I see:

| $ size drivers/usb/gadget/gadget_chips.o
| text    data     bss     dec     hex filename
| 1048       0       0    1048     418 drivers/usb/gadget/gadget_chips.o

That is almost a KiB which is removed from each user.
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
  implemented in musb itself if it is correct)
- unique BCD accross all UDCs. Not sure how important this is.

 It's touches a lot of different parts of the kernel, all USB drivers,

 some changes that are needed for USB 3.0 power management updates.
 
 There are also lots of new drivers, pimarily gadget, but others as well.
 We deleted a staging driver, which was nice, and finally dropped the
 obsolete usbfs code, which will make Al happy to never have to touch
 that again.
 
 There were some build errors in the tree that linux-next found a few
 days ago, but those were fixed by the most recent changes (all were due
 to us not building with CONFIG_PM disabled.)

bc25a80d12 usb: move ci13xxx and related code to drivers/usb/chipidea
Since chipidea is a dual role controller, it makes sense to move it
to its own directory, where we can also have host, otg and platform
code related to this controller. It also makes sense to break out
the driver into several compilation units like udc, host, debugging
code, etc.

Firstly, let's move the udc and platform code to drivers/usb/chipidea.

c52661d60f usb-gadget: Initial merge of target module for UASP + BOT
This fabric uses the target framework to provide a usb gadget
device.  This gadget supports the USB Attached SCSI Protocol (UASP)
and Bulk Only Transfers (BOT or BBB). BOT is the primary interface,
UAS is the alternative interface.

It has been tested with dummy_hcd on HS and SS. On SS USB3 are
supported. I also took my omap device and tried it there against
WindowsXP.  UAS implements basic command passing (i.e. read/write
requests) and TASK MANAGEMENT functions are missing.

I had to add a little of error recovery to BOT because Windows was
issuing some strange commands and it does not complain after the
gadget responded with CSW.status=1.

(nab: Move to drivers/usb/gadget as per Sebastian to address legacy
      limitations for built-in gadget code)

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

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.

c6c5600851 USB: g_ffs: the FunctionFS gadget driver
The Function Filesystem (FunctioFS) lets one create USB
composite functions in user space in the same way as GadgetFS
lets one create USB gadgets in user space.  This allows
creation of composite gadgets such that some of the functions
are implemented in kernel space (for instance Ethernet, serial
or mass storage) and other are implemented in user space.

f176a5d812 USB: g_multi: Multifunction Composite Gadget added
The Multifunction Composite Gadget has two configurations
consisting of Ethernet (RNDIS in first and CDC Ethernet in
second configuration), CDC Serial and File-backed Storage
functions.

When connected to a Windows host, the first configuration
is chosen thus gadget provides RNDIS Ethernet, serial and
mass storage whereas when connected to Linux host, second
configuration is chosen thus providing CDC Ethernet,
serial and mass storage.

Which configurations are built can be configured via
KConfig options.

This patch adds support for i.MX3x (only tested with i.MX31 so far) ARM
SoCs to the fsl_usb2_udc driver. It also moves PHY configuration before
controller reset, because otherwise an ULPI PHY doesn't get a reset and
doesn't function after a reboot. The problem with longer control transfers
is still not fixed. The patch renames the fsl_usb2_udc.c file to
fsl_udc_core.c to preserve the same module name for user-space
backwards compatibility.

be as close as we can to "gcc --combine ...".

This is a bit more complicated than most of the others
because it had to resolve a few symbol collisions.
