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

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.

The FunctionFS gadget may provide the source/sink interface
not as the first interface (with id == 0) but some different
interface hence a code to find the interface number is
required.
(Note that you will still configure the gadget to report
idProduct == 0xa4a4 (an "echo 0xa4a4

configure host to handle 0x0525:0xa4ac devices using the

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.

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.
When all files are closed the function disables itself.
