This patch (as883) removes an out-of-date WARN_ON from the main HCD
endpoint-disable routine. The warning is triggered whenever an
endpoint is disabled while the root hub is suspended. In the past
that may not have been legal, but it definitely is legal now. Merely
unbinding a USB driver will do it.
Furthermore, I've never seen any occurrences of this warning that
really did signal an actual bug or error condition. At this point it
has outlived its purpose.

This patch (as879) ties up some loose ends from an earlier patch.
These are things I didn't think to include at the time but which
clearly belonged there.
If an autosuspend fails because driver activity races with
the autosuspend call, restart the autosuspend timer.
When a device is resumed by an external request, it counts
as device activity and should update the last_busy time so
that the next autoresume won't occur immediately.

This patch (as882) fixes a problem with the EHCI BIOS handoff. On my
machine, the BIOS configures the controller and the handoff fails,
leaving the controller configured. During resume-from-disk, this
confuses ehci-hcd into thinking that the controller has not been
tampered with.
The problem is fixed by turning off the Configured Flag whenever a
BIOS handoff is attempted, whether it succeeds or not.

It is preferable to group drivers by usage (net, scsi, ATA, ...) than
by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer
is probably less qualified on networking issues than a networking
maintainer. Also, from a practical standpoint, chips often
appear on multiple buses, which is why we do not put drivers into
drivers/pci/net.

The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.
The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.

Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after
a modprobe. Until now, an application had to loop until a new bus could
be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly
to which bus a specific device is attached.
Paolo Albeni provided the original concept implementation. I added the
handling of "bus->monitored" flag and generally fixed it up.

This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework. Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value. And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.
The patch also makes some related minor improvements:
Move the calls to the autosuspend condition-checking routine
into usb_suspend_both(), which is the only place where it
really matters.
If the autosuspend timer is already running, don't stop
and restart it.
Replace immediate returns with gotos so that the optional
debugging ouput won't be bypassed.
If autoresume is disabled but the device is already awake,

o The "real" usb-devices export now a device node which can
populate /dev/bus/usb.
o The usb_device class is optional now and can be disabled in the
kernel config. Major/minor of the "real" devices and class devices
are the same.
o The environment of the usb-device event contains DEVNUM and BUSNUM to
help udev and get rid of the ugly udev rule we need for the class
devices.
o The usb-devices and usb-interfaces share the same bus, so I used
the new "struct device_type" to let these devices identify
themselves. This also removes the current logic of using a magic
platform-pointer.
The name of the device_type is also added to the environment
which makes it easier to distinguish the different kinds of devices
on the same subsystem.
It looks like this:
add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1
ACTION=add
DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1
SUBSYSTEM=usb
SEQNUM=1533
MAJOR=189
MINOR=131
DEVTYPE=usb_device
PRODUCT=46d/c03e/2000
TYPE=0/0/0
BUSNUM=002
DEVNUM=004
This udev rule works as a replacement for usb_device class devices:
SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \
NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644"
Updated patch, which needs the device_type patches in Greg's tree.

As part of the change, it turns out to be necessary to do remote

does autoresume rather than an external resume. Using the

If this link is not appropriate I'd have to create device files in

This patch removes the unnecessary bit number from CKENnn_XXXX
definitions for PXA, so that
CKEN0_PWM0 --> CKEN_PWM0
CKEN1_PWM1 --> CKEN_PWM1
...
CKEN24_CAMERA --> CKEN_CAMERA
The reasons for the change of these defitions are:
1. they do not scale - they are currently valid for pxa2xx, but
definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
instead of bit 24
2. they are unnecessary - the peripheral name within the definition
has already announced its usage, we don't need those bit numbers
to know which peripheral we are going to enable/disable clock for
3. they are inconvenient - think about this: a driver programmer
for pxa has to remember which bit in the CKEN register to turn
on/off
Another change in the patch is to make the definitions equal to its
clock bit index, so that
#define CKEN_CAMERA (24)
instead of
#define CKEN_CAMERA (1 << 24)
this change, however, will add a run-time bit shift operation in
pxa_set_cken(), but the benefit of this change is that it scales
when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
and so that pxa_set_cken() need minimum change to adapt to that.

system must poll for the end of the sequence.

Various fixes to omap_udc, noted with some recent testing:
- Cope with some SMP-induced braindamage in ARM's dma_{alloc,free}_coherent()
implementation: alloc() can be called with IRQs blocked, but since late
last year that's no longer true for free(). This resolves really NASTY
problems with logspamming via WARN_ON(), indicating N-page leaks.
- Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the
previous code only handled RECIP_INTERFACE, this version should be correct
except for (sigh) bulk/interrupt endpoints.
- Provide a better name for the function reporting whether the board has
vbus sensing wired up.
GET_STATUS requests for endpoint status still acts strangely though, at least
given one flakey host doesn't always ack the first DATA packet, then the packet
that gets retransmitted doesn't have data!

I encountered some problems with the airprime driver in use with a Novatel
Merlin XU870:
Closing an open Connection to e.g. /dev/ttyUSB0 doesn't reset the
RTS/DTR lines of the Modem. Consequently, when I use minicom to
establish a connection by "ATD*99#" the modem doesn't hang up even if i
exit minicom and so I cannot reuse the modem unless I remove it and plug
it in again.
With the attached patch, the RTS/DTR lines are resetted on a close. The
code was mainly taken from the option.c driver.
Convert all the port specific code in attach / shutdown to use the new
port_probe / port_register callbacks from device_register /
device_unregister allowing adding the sysfs attributes to be added at
the correct time and to the serial port device itself, instead of to
the unadorned usb device, avoiding a NULL dereference.

Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird
non-standard way - it contains multiple reports with the same usage, which
results in remapping of GenericDesktop.X and GenericDesktop.Y usages to
GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the
touchwheel unusable.
The commit 3506897691 solved this
in a way that it didn't remap certain usages. This however breaks
(at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210),
which in contrary requires the remapping.
To make both of the harware work, allow remapping of these usages again,
and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we

This patch (as856) attempts to improve the performance of uhci-hcd by
removing the asynchronous skeleton Queue Headers. They don't contain
any useful information but the controller has to read through them at
least once every millisecond, incurring a non-zero DMA overhead.
Now all the asynchronous queues are combined, along with the period-1
interrupt queue, into a single list with a single skeleton QH. The
start of the low-speed control, full-speed control, and bulk sublists
is determined by linear search. Since there should rarely be more
than a couple of QHs in the list, the searches should incur a much
smaller total load than keeping the skeleton QHs.

backlight_device->sem has a very specific use as documented in the

reason, to serialise access to the update_status() method.
backlight users were supposed to implement their own internal
serialisation of update_status() if needed but everyone is doing
things differently and incorrectly. Therefore add a global mutex to
take care of serialisation for everyone, once and for all.
Locking for get_brightness remains optional since most users don't

Some USB devices do have a configuration 0, in contravention of the
USB spec. Normally 0 is supposed to indicate that a device is
unconfigured.
While we can't change what the device is doing, we can change usbcore.
This patch (as852) allows usb_set_configuration() to accept a config
value of -1 as indicating that the device should be unconfigured. The
request actually sent to the device will still contain 0 as the value.
But even if the device does have a configuration 0, dev->actconfig
will be set to NULL and dev->state will be set to USB_STATE_ADDRESS.
Without some sort of special-case handling like this, there is no way
to unconfigure these non-compliant devices.

A SET_LINE_CODING control request should return a zero length packet
as an ACK to the host, during the status phase of a USB transaction.
The return value of gs_setup_class() is treated as the number of
bytes to write in the status phase of the control request, by
gs_setup(). For this case, the value returned by gs_setup_class should
be zero for SET_LINE_CODING but, right now, appears to be
sizeof(struct usb_cdc_line_coding).
However, if after doing the memcpy of the line coding descriptor we
set the variable "ret" to be zero, we should return the appropiate ZLP
to the host as an ACK in the status phase of the control request.
I've tested this out using Linux as both host and slave and confirmed
that the following small change fixes the spurious return of
sizeof(struct usb_cdc_line_coding)/wLength bytes in the status phase
of a USB_CDC_REQ_SET_LINE_CODING request. It's not a huge bug but, it

there's a USB mass storage device which exists in two version. One
reports the correct size and the other does not. Apart from that they
are identical and cannot be told apart. Here's a heuristic based on the
empirical finding that drives have even sizes.

as the skeleton driver was made ready for autosuspend a race condition
was introduced. The reference to get device must be gotten before the
autosuspend counter is upped, as this operation may sleep, dropping BKL.
Dropping BKL means that the pointer to the device may become invalid.
Here's the fix.

This patch (as849) fixes a bug in the USB hub driver. A single
pre-allocated buffer is used for all port status reads, but nothing
guarantees exclusive use of the buffer. A mutex is added to provide
this guarantee.

Fix up the error processing path: in usb_submit_urb failed, we forgot
to free buffers. Also, don't free buffers in read callback: less error
prone, 21 LOC less, no need to comment so much. N.B. write path is ok
to do kfree.

This patch (as847) makes some small changes to the hub driver's
suspend method:
For root hubs, the status URB should be unlinked and other
activity stopped _before_ the bus_suspend method is called.
The test for hdev->bus being NULL has been removed, since
it can never succeed.

I added two fields to struct usb_serial_port to keep track of the
throttle state. Other usb-serial drivers typically use private data for
such things, but the generic driver can not really do that because some
of its code is also used by other drivers (which may have their own
private data needs).
As it is, I am not sure that this patch is useful in all scenarios.
It is certainly helpful for low-bandwidth devices that can hold their
data in response to throttling. But for devices that pump data in
real-time as fast as possible (webcam, A/D converter, etc), throttling
may actually cause more data loss.

in devices.c we have a piece of code for dealing with losing in a race.
If we indeed lose the race we don't care whether our own memory allocation
worked. The check for that is so early that we return early even if we
don't have to.

A simple driver to turn on the charging capability of a USB BlackBerry
device when it is plugged into the machine. It does not bind to the
device, so all userspace programs can still sync properly with it.
Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this
device as the power to the port will be shut down. This device id will
have to be added to the global blacklist table when it is created.

This patch (as850b) disables remote wakeup (and everything else!) on

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.
