Andy Gay 5dda171202 USB: Airprime driver improvements to allow full speed EvDO transfers
Adapted from an earlier patch by Greg KH <gregkh@suse.de>.
That patch added multiple read urbs and larger transfer buffers to allow
data transfers at full EvDO speed.

This version includes additional device IDs and fixes a memory leak in
the transfer buffer allocation.

Some (maybe all?) of the supported devices present multiple bulk endpoints,
the additional EPs can be used for control and status functions,
This version allocates 3 EPs by default, that can be changed using
the 'endpoints' module parameter.

Tested with Sierra Wireless EM5625 and MC5720 embedded modules.

Device ID (0x0c88, 0x17da) for the Kyocera Wireless KPC650/Passport
was added but is not yet tested.

David Brownell 26f953fd88 USB: EHCI update VIA workaround
This revamps handling of the hardware "async advance" IRQ, and its watchdog
timer.  Basically it dis-entangles that important timeout from the others,
simplifying the associated state and code to make it more robust.

This reportedly improves behavior of EHCI on some systems with VIA chips,
and AFAIK won't affect non-VIA hardware.  VIA systems need this code to
recover from silcon bugs whereby the "async advance" IRQ isn't issued.

This patch(as785) forces the PM core to resume a root hub after a

Pete Zaitcev 71795c1df3 USB: ohci_usb can oops on shutdown
When ohci-hcd is shutting down (for rmmod or PC-card removal), there is
a window when the device is shut down, HC communication area (->hcca)
is freed, but the core has not called "free_irq" yet. If another device
triggers a shared interrupt in this window, we oops when trying to
access the freed ->hcca.

This patch removes the window by calling free_irq before ->hcca is freed.

The patch is tested at the PC hotplug test rig at Stratus, and with
rmmod by Rafael Wysocki.

Pete Zaitcev 38e2bfc94e USB: Dealias -110 code (more complete)
The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".

The usbmon splits such cases already thanks to its timestamp, but
it's not always available.

I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

Tony Olech d774efeabc USB: u132-hcd: host controller driver for ELAN U132 adapter
This "u132-hcd" module is one half of the "driver" for
ELAN's U132 which is a USB to CardBus OHCI controller
adapter. This module needs the "ftdi-elan" module in
order to communicate to CardBus OHCI controller inserted
into the U132 adapter.

When the "ftdi-elan" module detects a supported CardBus
OHCI controller in the U132 adapter it loads this "u132-hcd"
module.

Upon a successful device probe() the single workqueue
is started up which does all the processing of commands
from the USB core that implement the host controller.

The workqueue maintains the urb queues and issues commands
via the functions exported by the "ftdi-elan" module. Each
such command will result in a callback.

Note that the "ftdi-elan" module is a USB client driver.

Note that this "u132-hcd" module is a (cut-down OHCI)
host controller.

Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem
semaphore/mutex handling in the module removal.

Tony Olech a5c66e4b24 USB: ftdi-elan: client driver for ELAN Uxxx adapters
This "ftdi-elan" module is one half of the "driver" for
ELAN's Uxxx series adapters which are USB to PCMCIA CardBus
adapters. Currently only the U132 adapter is available and
it's module is called "u132-hcd".

When the USB hot plug subsystem detects a Uxxx series adapter
it should load this module.

Upon a successful device probe() the jtag device file interface
is created and the status workqueue started up.

The jtag device file interface exists for the purpose of
updating the firmware in the Uxxx series adapter, but as
yet it had never been used.

The status workqueue initializes the Uxxx and then sits there
polling the Uxxx until a supported PCMCIA CardBus device is
detected it will start the command and respond workqueues
and then load the module that handles the device. This will
initially be only the u132-hcd module. The status workqueue
then just polls the Uxxx looking for card ejects.

The command and respond workqueues implement a command
sequencer for communicating with the firmware on the other
side of the FTDI chip in the Uxxx. This "ftdi-elan" module
exports some functions to interface with the sequencer.

Note that this module is a USB client driver.

Note that the "u132-hcd" module is a (cut-down OHCI)
host controller.

Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem

Mike Isely 78aef519ed cypress_m8: implement graceful failure handling
When receiving a fatal error from the USB core, e.g. EILSEQ (which can
happen if the polling interval is too short), fail gracefully.
Previously the driver would fill the log with useless error messages
or (more alarmingly) silently spin forever trying to write updated
control information to the device.  This change implements a new flag
which if cleared indicates that the driver has failed.  The flag will
be set on initialization, cleared on fatal errors, and anything else
that touches the USB port in the driver will abort if the flag is
clear.  When the flag is cleared, a message will be logged indicating
that the driver has failed.

Rather than directly filling in URB fields, it's safer to use
usb_fill_int_urb().  This improves robustness of the driver; URB
changes in the future will not go uninitialized here.  That point not

use usb_fill_int_urb() everywhere or don't bother with it all.

Mike Isely 0257fa9ffe cypress_m8: use appropriate URB polling interval
The polling interval for the device can't always be 1msec.  If it is
too quick, the device can fail causing a fatal (to the driver) EILSEQ
error from the USB core.  The actual correct value is reported by the
device as part of its configuration data, so use that value as the
default.  On a DeLorme Earthmate for example, the device reports that
it wants a 6msec interval.  As part of this fix, the "interval" module
option has been fixed as well; the device's default can be overridden
by specifying interval=<value> as a module option.

This patch (as739) adds the basic infrastructure for USB autosuspend
and autoresume.  The main features are:

	PM usage counters added to struct usb_device and struct
	usb_interface, indicating whether it's okay to autosuspend
	them or they are currently in use.

	Flag added to usb_device indicating whether the current
	suspend/resume operation originated from outside or as an
	autosuspend/autoresume.

	Flag added to usb_driver indicating whether the driver
	supports autosuspend.  If not, no device bound to the driver
	will be autosuspended.

	Mutex added to usb_device for protecting PM operations.
	Unlike the device semaphore, the locking rule for the pm_mutex
	is that you must acquire the locks going _up_ the device tree.

	New routines handling autosuspend/autoresume requests for
	interfaces and devices.

	Suspend and resume requests are propagated up the device tree
	(but not outside the USB subsystem).

	work_struct added to usb_device, for carrying out delayed
	autosuspend requests.

	Autoresume added (and autosuspend prevented) during probe and
	disconnect.

ignores it.

Since we're on it, let cdrecord access a device when ->changed is set.

significant limitations of the dma framework (memory wastage for buffers

So count this as two steps forward (bugfixes:  the latter issue could cause
errors on some platforms, and some MIPS changes broke code for the former), 
and one step back (increasing cross-platform memory wastage).

Plus linelength and whitespace fixes; and minor data segment shrinkage.

David Brownell 729ed6d502 USB: ethernet gadget avoids zlps for musb_hdrc
For systems using the Mentor HDRC controllers we get better TX DMA throughput
if we can avoid falling back to PIO to write zero length packets ... so tell
the driver to avoid ZLPs.

Alan Stern 4d6cd48380 usbmon: don't call mon_dmapeek if DMA isn't being used
This patch (as755b) fixes a bug in usbmon.  Rather than assuming all
USB host controllers use DMA, the code will check the usb_bus data
structure.  If DMA isn't used, we don't want to try peeking into a
non-existent DMA buffer!

Alan Stern 1720058343 usbcore: trim down usb_bus structure
As part of the ongoing program to flatten out the HCD bus-glue layer,
this patch (as771b) eliminates the hcpriv, release, and kref fields
from struct usb_bus.  hcpriv and release were not being used for
anything worthwhile, and kref has been moved into the enclosing
usb_hcd structure.

Along with those changes, the patch gets rid of usb_bus_get and
usb_bus_put, replacing them with usb_get_hcd and usb_put_hcd.

The one interesting aspect is that the dev_set_drvdata call was
removed from usb_put_hcd, where it clearly doesn't belong.  This means
the driver private data won't get reset to NULL.  It shouldn't cause
any problems, since the private data is undefined when no driver is
bound.

Alan Stern dd990f16a3 usbcore: Add flag for whether a host controller uses DMA
This patch (as770b) introduces a new field to usb_bus: a flag
indicating whether or not the host controller uses DMA.  This serves
to encapsulate the computation.  It also means we will have only one
spot to update if the DMA API changes.

Alan Stern a6d2bb9ff9 USB: remove struct usb_operations
All of the currently-supported USB host controller drivers use the HCD
bus-glue framework.  As part of the program for flattening out the glue
layer, this patch (as769) removes the usb_operations structure.  All
function calls now go directly to the HCD routines (slightly renamed
to remain within the "usb_" namespace).

The patch also removes usb_alloc_bus(), because it's not useful in the
HCD framework and it wasn't referenced anywhere.
