This is an update to the AT91 USB Device (Gadget) driver.
Adds support for the Atmel AT91SAM9260 and AT91SAM9261 processors. The
only difference is how they handle the pullup pin.
[Patch from Patrice Vilchez]
Need to clear any pending USB Device interrupts before registering the
interrupt handler. The bootloader might have been using the USB Device
port. [Patch from Peer Georgi]
VBUS detection is handled by a GPIO interrupt which only triggers on a
change. Is is therefore necessary to read the current VBUS state
explicitly at startup. [Patch from Peer Georgi]

This is an update to the AT91 USB Device (Gadget) driver.
The base I/O address provided in the platform_device resources is now
ioremap()'ed instead of using a statically mapped memory area. This
helps portability to the newer AT91sam926x processors.
The major change is that we now have to pass a 'struct at91_udc'
parameter to at91_udp_read() and at91_udp_write().

I have found a problem where the root_port_reset() goes into an infinite
loop and stalls the kernel.
This happens when a hardware fault inside the machine occurs during a small
timing window. In case of USB device connection, if a USB device responds to
hcd_submit_urb(), and later the controller fails before root_port_reset(),
root_port_reset() will loop infinitely because ohci_readl() will always
return "-1". Such a failure can include ejecting a CardBus OHCI controller.
The probability of this problem is low, but it will increase if PnP type
usage is frequent. The attached patch can solve this problem and I believe
that it is better to fix this problem.

Allow gadget drivers to omit the unbind() method. When they're
statically linked, that's an appropriate memory saving tweak.
Similarly, provide consistent/simpler handling for a should-not-happen
error case: removing a peripheral controller driver when a gadget
driver is still loaded. Such code dates back to early versions of the
first implementation of the gadget API, and has never been triggered.
Includes relevant section annotation fixs for gmidi.c, file_storage.c,
and serial.c; we don't yet have an "init or exit" annotation. Also
some whitespace fixes in gmidi.c (space at EOL, before tabs, etc).

Certain boards seem to like to issue false overcurrent notifications,
for example on ports that don't have anything connected to them. This
looks like a hardware error, at the level of noise to those ports'
overcurrent input signals (or non-debounced VBUS comparators). This
surfaces to users as truly massive amounts of syslog spam from khubd
(which is appropriate for real hardware problems, except for the
volume from multiple ports).
Using this new "ignore_oc" flag helps such systems work more sanely,
by preventing such indications from getting to khubd (and spamming
syslog). The downside is of course that true overcurrent errors will
be masked; they'll appear as spontaneous disconnects, without the
diagnostics that will let users troubleshoot issues like
short-circuited cables. In addition, controllers with no devices
attached will be forced to poll for new devices rather than relying on
interrupts, since each overcurrent event would generate a new
interrupt.
This patch (as826) is essentially a copy of David Brownell's ignore_oc
patch for ehci-hcd, ported to uhci-hcd.

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=7508
When the Nokia E70 Phone is plugged in to the USB port, I get:
end_request: I/O error, dev sda, sector 1824527

end_request: I/O error, dev sda, sector 1824535
sd 0:0:0:0: SCSI error: return code = 0x10070000
The fix is to add these lines to drivers/usb/storage/unusual_devs.h:

When u132-hcd is built, it includes local header ohci.h, which appears
to have been intended only for use by ohci-hcd.
This throws warnings about functions which are defined and not used.
The warnings thrown are because three small functions are implemented in
the header, but not declared 'inline', a rather strange affair.
Since these functions are small, let's go ahead and define them as
'inline', just like the inline functions surrounding them. This makes
things more consistent, and kills the warnings.

Added a device specific ioctl function to prevent the disabling of canonical
mode. EINVAL is returned for any TCSETSF ioctl that doesn't have ICANON set.
This patch is for 2.6.17 or later kernels.
When "hwinfo --modem" is executed it opens the funsoft USB serial device and
disables canonical mode. The device is kept this way until hwininfo has
finished probing any modems on a system. The funsoft device expects to be
running in canonical mode. Switching the device to raw mode can cause
incomplete data packets and device timeouts.

There was an off-by-one bug in bnx2_tx_avail(). If the tx ring is
completely full, the producer and consumer indices may be apart by
256 even though the ring size is only 255. One entry in the ring is
unused and must be properly accounted for when calculating the number
of available entries. The bug caused the tx ring entries to be
reused by mistake, overwriting active entries, and ultimately causing
it to crash.
This bug rarely occurs because the tx ring is rarely completely full.
We always stop when there is less than MAX_SKB_FRAGS entries available
in the ring.

The UDMA66 VIA hardware has no controller side cable detect bits we can
use. This patch minimally fixes the problem by reporting unknown in this
case and using drive side detection.
The old drivers/ide code does some additional tricks but those aren't
appropriate now we are in -rc.
Without this update UDMA66 via controllers run slowly. They don't fail so
it's a borderline call whether this is -rc material or not.
