Rename WARN() to WARNING() to clear the namespace

2008-07-25T17:53:29+00:00

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.

usb ethernet gadget: use composite gadget framework

2008-07-21T22:16:17+00:00

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.

usb gadget: RNDIS cleanups

2008-07-21T22:16:10+00:00

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).

[ARM] 5120/1: pxa: correct platform driver names for PXA25x and PXA27x UDC drivers

2008-07-09T20:30:13+00:00

The pxa2xx_udc.c driver is renamed to pxa25x_udc.c (the platform
driver name changes from pxa2xx-udc to pxa25x-udc) and the
platform driver name of pxa27x_udc.c is fixed to pxa27x-udc.
pxa_device_udc in devices.c is split into pxa25x and pxa27x flavors
and the pxa27x_device_udc is enabled in pxa27x.c.

usb: pxa27x_udc driver

2008-05-02T17:25:53+00:00

Adds pxa27x udc driver to support USB peripherals on pxa27x chips.

The driver is compatible with: Gadget Zero, the File Storage
gadget, and the Ethernet gadget (only in CDC subset mode).

The driver can't properly support multiple interfaces, because
of hardware bugs without possible workaround.  That means no
RNDIS support from g_ether, and no CDC ACM support in g_serial.

USB: gadget section fixes

2008-04-25T04:16:48+00:00

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.

USB: gadget: queue usb USB_CDC_GET_ENCAPSULATED_RESPONSE message

commit 0cf4f2de0a0f4100795f38ef894d4910678c74f8 introduced a bug, which
prevents sending an USB_CDC_GET_ENCAPSULATED_RESPONSE message. This
breaks the RNDIS initialization (especially / only Windoze machines
dislike this behavior...).
