836e4b14b4 USB: m66592-udc: Fix up dev_set_name() badness.
Commit 0031a06e2f converted all of the USB
drivers to use dev_set_name(), though there was a typo on the m66592-udc
conversion that handed off the wrong pointer (we want the struct device
here obviously, not the struct usb_gadget).

b6c6393700 Rename WARN() to WARNING() to clear the namespace
We want to use WARN() as a variant of WARN_ON(), however a few drivers are
using WARN() internally.  This patch renames these to WARNING() to avoid the
namespace clash.  A few cases were defining but not using the thing, for those
cases I just deleted the definition.

0391c828ce usb ethernet gadget: use composite gadget framework
Building on the previous patches which took code from this driver and
pakaged it in more-reusable network "function" components, this patch
gets rid of the original code and uses those components instead.

As seen with the other gadget driver conversions, the resulting code
is much easier to understand and (presumably) work with.  In this case
that's especially true, since the Ethernet gadget had grown to handle
three (!) different Ethernet-over-USB protocols.  This modularization
should make it much easier to add a fourth option for the newish CDC
"Ethernet Emulation Model" (or EEM).

Lightly tested, primarily at full speed.

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:

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.

15b2d2b529 usb gadget: RNDIS cleanups
Some cleanup to the RNDIS code:

 - Minor bugfix:  rndis_unit() is supposed to put the link into the
   RNDIS_UNINITIALIZED state, which does not mean "unused".  There's
   a separate method to stop using the link.  (Bug doesn't affect
   anything right now because of how the code is used.)

 - Reduce coupling between RNDIS code and its user(s), in preparation
   for updates in that code:

    * Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device
      by passing just a void* handle.  (Also, remove the unused return
      value of the notification callback.)
    * When it needs a copy of net_device stats, just ask for it

 - Remove unused/untested code backing various never-used OIDs:

    * RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the
      relevant docs were unclear, ambguous, and incomplete.  Someone
      with access to the Hidden Gospels (maybe in the EU?) might be
      able to figure out what this should do.
    * RNDIS_OPTIONAL_STATS ... as the name suggests, optional.  Never
      implemented in part because not all the semantics were clear.
    * OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever.

 - A few small whitespace fixes

Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style.

There should be no functional changes because of this patch; it's a
net source code shrink (because of the dead/unused code removal) and
a small object code shrink (a couple hundred bytes on ARMv5).

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.

40982be52d usb gadget: composite gadget core
Add <linux/usb/composite.h> interfaces for composite gadget drivers, and
basic implementation support behind it:

  - struct usb_function ... groups one or more interfaces into a function
    managed as one unit within a configuration, to which it's added by
    usb_add_function().

  - struct usb_configuration ... groups one or more such functions into
    a configuration managed as one unit by a driver, to which it's added
    by usb_add_config().  These operate at either high or full/low speeds
    and at a given bMaxPower.

  - struct usb_composite_driver ... groups one or more such configurations
    into a gadget driver, which may be registered or unregistered.

  - struct usb_composite_dev ... a usb_composite_driver manages this; it
    wraps the usb_gadget exposed by the controller driver.

This also includes some basic kerneldoc.

How to use it (the short version):  provide a usb_composite_driver with a
bind() that calls usb_add_config() for each of the needed configurations.
The configurations in turn have bind() calls, which will usb_add_function()
for each function required.  Each function's bind() allocates resources
needed to perform its tasks, like endpoints; sometimes configurations will
allocate resources too.

Separate patches will convert most gadget drivers to this infrastructure.

a4c39c41bf usb gadget: descriptor copying support
Define three new descriptor manipulation utilities, for use when
setting up functions that may have multiple instances:

	usb_copy_descriptors() to copy a vector of descriptors
	usb_free_descriptors() to free the copy
	usb_find_endpoint() to find a copied version

These will be used as follows.  Functions will continue to have static
tables of descriptors they update, now used as __initdata templates.

When a function creates a new instance, it patches those tables with
relevant interface and string IDs, plus endpoint assignments.  Then it
copies those morphed descriptors, associates the copies with the new
function instance, and records the endpoint descriptors to use when
activating the endpoints.  When initialization is done, only the copies
remain in memory.  The copies are freed on driver removal.

This ensures that each instance has descriptors which hold the right
instance-specific data.  Two instances in the same configuration will
obviously never share the same interface IDs or use the same endpoints.
Instances in different configurations won't do so either, which means
this is slightly less memory-efficient in some cases.

This also includes a bugfix to the epautoconf code that shows up with
this usage model.  It must replace the previous endpoint number when
updating the template descriptors, not just mask in a few more bits.

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.

c1dca562be usb gadget: split out serial core
This abstracts the "gadget serial" driver TTY glue into a separate
component, cleaning it up and disentangling it from connection state.

It also changed some behaviors for the better:

  - Stops using "experimental" major #127, and switches over to
    having the TTY layer allocate the dev_t numbers.
    
  - Provides /sys/class/tty/ttyGS* nodes, thus mdev/udev support.
    (Note "mdev" hotplug bug in Busybox v1.7.2: /dev/ttyGS0 will
    be a *block* device without CONFIG_SYSFS_DEPRECATED_V2.)

  - The tty nodes no longer reject opens when there's no host.
    Now they can support normal getty configs in /etc/inttab...

  - Now implements RX throttling.  When the line discipline says
    it doesn't want any more data, only packets in flight will be
    delivered (currently, max 1K/8K at full/high speeds) until it
    unthrottles the data.

  - Supports low_latency.  This is a good policy for all USB serial
    adapters, since it eliminates scheduler overhead on RX paths.

This also includes much cleanup including better comments, fixing
memory leaks and other bugs (including some locking fixes), messaging
cleanup, and an interface audit and tightening.  This added up to a
significant object code shrinkage, on the order of 20% (!) depending
on CPU and compiler.

A separate patch actually kicks in this new code, using the functions
declared in this new header, and removes the previous glue.

284d115ec9 [ARM] pxa: separate PXA25x and PXA27x UDC register definitions
The PXA25x and PXA27x USB device controller register definitions are
different.  Currently, they live side by side in pxa-regs.h, but only
one set is available depending on the setting of PXA25x or PXA27x.

This means that if we build to support both PXA25x and PXA27x, the
PXA27x definitions are unavailable, even to PXA27x specific code.

Remove these definitions from pxa-regs.h, and place them in separate
files.  Include these files where appropriate.

Note: according to the dependencies in drivers/usb/gadget/Kconfig,
we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
platform devices from pxa27x.c and pxa3xx.c.

4051770706 USB: atmel_usba_udc fixes, mostly disconnect()
Various fixes to Atmel's high speed UDC driver.

  * Issue some missing disconnect() calls.  Currently they are only made
    when VBUS power goes away (on boards where the driver can sense such
    changes), but that's not enough for gadget drivers to clean out all
    the state that's needed.  Missing calls were:

      - After USB reset, before starting enumeration.
      - When unregistering a gadget driver, before unbind().

  * Don't assume gadget drivers provide disconnect callbacks; make sure
    to not call through a null pointer!

  * When the driver doesn't provide an unbind() callback, refuse to
    unregister it.

Also remove two bogus "error" messages:

  * Related to mis-handling of disconnect() ... don't emit error messages
    for disconnect() handlers that disable endpoints.  All of them should
    be doing that; the problem is (unfixed) oddness in atmel_usba_udc.

  * Don't emit a diagnostic for a curious and transient nonfatal error
    that shows up sometimes with EP0.

Those messages spammed syslog, for no good reason.

 - Serial numbers that aren't specific to individual devices
   are useless; stop reporting "0" for this.

 - Since it's not part of a CDC-conformant function, the "bulk only"

This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.

Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

9079e91b5b USB: serial gadget: cleanup/reorg
Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.

 - Remove most forward declarations
     * put tty and gadget driver structs after their contents
     * snug module init/exit decls next to their functions
     * reordered some functions

 - Other cleanup:
     * convert a funky macro to an inline function
     * snug up module params next to their declarations
     * add missing driver.owner
     * add separator lines between major driver sections

 - Add comments re potential parameter/#define changes:
     * only supports one port (shrank GS_NUM_PORTS)
     * changing from 9600-8-N-1 affects multiple sites

 - Remove net2280-specific optimization ... it was being done
   way too late, can be done by net2280 module options, and in
   any case doesn't matter at any sane serial data rates.

There are no behavioral changes, but the macro thing saves I-space.

dynamically-allocated structures have a release method in the driver
core and are therefore immune to being released after the module has
been unloaded.

Thanks to Richard Purdie for pointing out the need for this change.

Restore some section annotations:  they were switched to "__devinit"
while they should have been "__init", because of bogus warnings.  The
warnings are now fixed, so the runtime footprint of various drivers
can now shrink a bit.  On ARMv5, it's about 600 bytes except for the
Ethernet gadget, where it can save a bit more.

This fixes bugs in blocking IO calls. When the poll() entry point

current receive buffer for data when reporting if any data had been
received. A memory leak was fixed that could have occurred when a

holes:

struct m66592 {

	/* sum members: 1192, holes: 2, sum holes: 4 */
	/* last cacheline: 12 bytes */

Pairing them gets back 4-bytes:

struct m66592 {
	...

	/* size: 1192, cachelines: 38 */
	/* last cacheline: 8 bytes */
};	/* definitions: 1 */

Unfortunately it's not enough to save a cacheline with this massive

This patch is part of the series adding support for the USB High
Speed Device Port on the AT91CAP9 system on chip. The AT91CAP9
uses the same UDPHS IP as the AVR32 and the AT91SAM9RL.

The only differences between the AVR32 and the AT91 version of the
device are in the enable/disable and suspend/wakeup sequences: the
AT91 version needs to toggle the USB bias and pulldown explicitly.

08cbc706ac USB: at91_udc: correct hanging while disconnecting usb cable
Correct hanging while disconnecting the USB device cable.  Prevent a race
between vbus and UDP interrupts.  This bug was tracked on at91sam9260ek
boards.

A usb resume interrupt was firing after the vbus interrupt : the IP was
then already stoped and not able to deal with it (no more clock).  A simple
interrupt disabling is ok as the "end of bus reset" irq is non maskable and
ok to resume the USB device IP.

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce

5395353e0c usb-gadget-ether: prevent oops caused by error interrupt race
Fix a longstanding race in the Ethernet gadget driver, which can cause an
oops on device disconnect.  The fix is just to make the TX path check
whether its freelist is empty.  That check is otherwise not necessary,
since the queue is always stopped when that list empties (and restarted
when request completion puts an entry back on that freelist).

The race window starts when the network code decides to transmit a packet,
and ends when hard_start_xmit() grabs the freelist lock.  When disconnect()
is called inside that window, it shuts down the TX queue and breaks the
otherwise-solid assumption that packets are never sent through a TX queue
that's stopped.

e9df41c5c5 USB: make HCDs responsible for managing endpoint queues
This patch (as954) implements a suggestion of David Brownell's.  Now
the host controller drivers are responsible for linking and unlinking
URBs to/from their endpoint queues.  This eliminates the possiblity of
strange situations where usbcore thinks an URB is linked but the HCD
thinks it isn't.  It also means HCDs no longer have to check for URBs
being dequeued before they were fully enqueued.

In addition to the core changes, this requires changing every host
controller driver and the root-hub URB handler.  For the most part the
required changes are fairly small; drivers have to call
usb_hcd_link_urb_to_ep() in their urb_enqueue method,
usb_hcd_check_unlink_urb() in their urb_dequeue method, and
usb_hcd_unlink_urb_from_ep() before giving URBs back.  A few HCDs make
matters more complicated by the way they split up the flow of control.

In addition some method interfaces get changed.  The endpoint argument
for urb_enqueue is now redundant so it is removed.  The unlink status
is required by usb_hcd_check_unlink_urb(), so it has been added to
urb_dequeue.

a4e3ef5597 USB: gadget: gadget_is_{dualspeed,otg} predicates and cleanup
This adds two small inlines to the gadget stack, which will
often evaluate to compile-time constants.  That can help
shrink object code and remove #ifdeffery.

 - gadget_is_dualspeed(), currently always a compile-time
   constant (depending on which controller is selected).

 - gadget_is_otg(), usually a compile time "false", but this
   is a runtime test if the platform enables OTG (since it's
   reasonable to populate boards with different USB sockets).

It also updates two peripheral controller drivers to use these:

 - fsl_usb2_udc, mostly OTG-related bugfixes:  non-OTG devices
   must follow the rules about drawing VBUS power, and OTG ones
   need to reject invalid SET_FEATURE requests.

 - omap_udc, just scrubbing a bit of #ifdeffery.

And also gadgetfs, which lost some #ifdefs and moved to a more
standard handling of DEBUG and VERBOSE_DEBUG.

The main benefits come from patches which will follow.

88e45dbbab USB: Stall control endpoint when file storage class request wValue != 0

some MSC compliance test warnings disappear.
