USB: EHCI: fix controller wakeup flag settings during suspend
This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers. When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.
In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops). This requires extra code, but the total delay
time is reduced.

This "feature" breaks suspend-resume if the root-hub is allowed

There is an undocumented register bit that can be used to disable

USB: isp1760: Soften DW3 X/transaction error bit handling
There were some reports[1] of isp1760 USB driver malfunctioning
with high speed devices, noticed on Blackfin and PowerPC targets.
These reports indicated that the original Philips 'pehcd'[2]
driver worked fine.
We've noticed the same issue with an ARM RealView platform. This
happens under load (with only some mass storage devices, not all,
just as in another report[3]):
error bit is set in DW3
error bit is set in DW3
error bit is set in DW3
usb 1-1.2: device descriptor read/64, error -32
It appears that the 'pehcd' driver checks the X bit only if the
transaction is halted (H bit), otherwise the error is so far
insignificant.
The ISP176x chips were modeled after EHCI, and EHCI spec says
(thanks to Alan Stern for pointing out):
"Transaction errors cause the status field to be updated to reflect
the type of error, but the transaction continues to be retried until
the Active bit is set to 0. When the error counter reaches 0, the
Halt bit is set and the Active bit is cleared."
So, just as the original Philips driver, isp1760 must report the
error only if the transaction error and the halt bits are set.

USB: gadget: Allow function access to device ID data during bind()
This is a patch that makes sure that the device ID data (idVendor,
idProduct and bcdDevice) are assigned to the descriptor in the cdev
structure *before* the composite gadget starts binding. This allows the
composite driver, and all the composite functions it uses, access to
that data.
In one of the composite functions we created, we needed to register an
input device and wanted to use the idVendor, idProduct and bcdDevice
codes to properly initialize the id field of the input device. We could
not do that because the idVendor, idProduct and bcdDevice values were
only set in the cdec structure *after* the composite->bind(cdev) call.

USB: f_fs: the FunctionFS driver
The FunctionFS is a USB composite function that can be used
with the composite framework to create an USB gadget.
>From kernel point of view it is just a composite function with
some unique behaviour. It may be added to an USB
configuration only after the user space driver has registered
by writing descriptors and strings (the user space program has
to provide the same information that kernel level composite
functions provide when they are added to the configuration).
>From user space point of view it is a file system which when
mounted provide an "ep0" file. User space driver need to
write descriptors and strings to that file. It does not need
to worry about endpoints, interfaces or strings numbers but
simply provide descriptors such as if the function was the
only one (endpoints and strings numbers starting from one and
interface numbers starting from core). The FunctionFS changes
numbers of those as needed also handling situation when
numbers differ in different configurations.
When descriptors and strings are written "ep#" files appear
(one for each declared endpoint) which handle communication on
a single endpoint. Again, FunctionFS takes care of the real
numbers and changing of the configuration (which means that
"ep1" file may be really mapped to (say) endpoint 3 (and when
configuration changes to (say) endpoint 2)). "ep0" is used
for receiving events and handling setup requests.

wait_event_interruptible_locked() interface
New wait_event_interruptible{,_exclusive}_locked{,_irq} macros added.
They work just like versions without _locked* suffix but require the
wait queue's lock to be held. Also __wake_up_locked() is now exported
as to pair it with the above macros.
The use case of this new facility is when one uses wait queue's lock
to protect a data structure. This may be advantageous if the
structure needs to be protected by a spinlock anyway. In particular,
with additional spinlock the following code has to be used to wait
for a condition:
spin_lock(&data.lock);
...
for (ret = 0; !ret && !(condition); ) {
spin_unlock(&data.lock);
ret = wait_event_interruptible(data.wqh, (condition));
spin_lock(&data.lock);
}
...
spin_unlock(&data.lock);
This looks bizarre plus wait_event_interruptible() locks the wait
queue's lock anyway so there is a unlock+lock sequence where it could
be avoided.
To avoid those problems and benefit from wait queue's lock, a code
similar to the following should be used:
/* Waiting */
spin_lock(&data.wqh.lock);
...
ret = wait_event_interruptible_locked(data.wqh, (condition));
...
spin_unlock(&data.wqh.lock);
/* Waiting exclusively */
spin_lock(&data.whq.lock);
...
ret = wait_event_interruptible_exclusive_locked(data.whq, (condition));
...
spin_unlock(&data.whq.lock);
/* Waking up */
spin_lock(&data.wqh.lock);
...
wake_up_locked(&data.wqh);
...
spin_unlock(&data.wqh.lock);
When spin_lock_irq() is used matching versions of macros need to be
used (*_locked_irq()).

Reimplement fifo-based writes in the generic driver using a multiple

In contrast to multi-urb writes, no allocations (of urbs or buffers) are
made during run-time and there is less pressure on the host stack
queues as currently only two urbs are used (implementation is generic
and can handle more than two urbs as well, though).
Initial tests using ftdi_sio show that the implementation achieves the
same (maximum) throughput at high baudrates as multi-urb writes. The CPU
usage is much lower than for multi-urb writes for small write requests
and only slightly higher for large (e.g. 2k) requests (due to extra copy
via fifo?).
Also outperforms multi-urb writes for small write requests on an
embedded arm-9 system, where multi-urb writes are CPU-bound at high
baudrates (perf reveals that a lot of time is spent in the host stack
enqueue function -- could perhaps be a bug as well).
Keeping the original write_urb, buffer and flag for now as there are

USB: usbserial: mos7720: add support for parallel port on moschip 7715
Add support for the parallel port on the moschip MCS7715 device. The port
registers itself with the parport subsystem as a low-level driver. A separate
entry to the kernel configuration is added beneath that for the mos7720, to
avoid the need to link with the parport subsystem code for users who don't have
or don't want the parallel port. Only compatibility mode is currently supported
(no ECP/EPP). Tested with both moschip devices (7720 and 7715) on UP and SMP
hosts, including regression testing of serial port, concurrent operation of
serial and parallel ports, and various connect / disconnect scenarios.
