.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.

This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers. There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical). Furthermore, only seven
drivers used it. We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.
The DMA-mapping portion of hcd.c is currently in flux. A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down. The removal should go smoothly,
as by then nobody will be using it.

Standard AT keyboard driver (atkbd) will be used on top of the serio layer for
handling the E3 keyboard (called mailboard) connected to the port. Since the
device generated scancodes differ from what the atkbd expects, a custom key
code to scan code table must be loaded from userspace for the keyboard to be

to external capacitance sensors implementing functions such as buttons,

The chips don't restrict the specific usage. Depending on the hardware
connection, one special target board can include one or several these

these information. The data-struct defined in head file descript the
hardware feature of button/scrollwheel/slider/touchpad components on

As the result, the driver is independent of boards. It gets the

Touch enbaled devices share the same product ID with pen. However,
we do not want to post touch events while pen is in prox. To do so,
we used to keep a local static variable to keep track of if pen is
in prox or not. This works fine for Tablet PC devices since there
is only one device attached. With the newer touch enabled regular
tablets, we can not make this assumption any more, i.e, one system
may have more than one identical tablet plugged in.
This patch adds an new entry, shared, into the struct wacom_wac so
touch data can access pen data to locally. This solution assumes
the two tools (touch and pen) of the same ID will be probed one
after the other without interruption in between by another Wacom
device of the same ID.

percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

When reading data from Geyser 2 touchpads used on post Oct 2005 Apple
PowerBooks the driver was casting X and Y coordinates values to
'signed char'. Testing on one of such PowerBooks I have noticed that
touchpad always generates positive values, but some of them are greater
that 127, and thus, when cast to 'signed char' being interpreted as
a negative.
Such bigger values have been observed infrequently, closer to the
edges of a touchpad, so the problem was not very visible.
Nevertheless, the patch would potentially improve touchpad

The time interval between consecutive interrupts depends on a number of
tunables: first_conversion_delay, acquisition_time, averaging and foremost
the pen_down_acc_interval.
Since the mod_timer() action for the PEN UP event happens in the
spi_async() callback function, latencies incurred by the spi bus drivers
also need to be taken into account.
So all in all, give the PEN UP event a bit more wiggle room and increase

When polled input device is opened and closed and there are no other
users of polled device, the workqueue is created and destroyed in
every open / close operation. It is probable that at some point
dynamic allocation of internal parts of the workqueue cause changes to the
workqueue.
When a work is queued to the workqueue the work struct contains pointers
to the workqueue data. If the workqueue has been changed and the work
has never been queued to the new workqueue, work-struct contains pointers
to the non-existing workqueue. This will cause crash at the work
cancellation during device close since cancellation of a work assumes
that the workqueue exists.
To prevent that, work struct is cleaned up at device close. This keeps
work struct clean for the next use.

The peripheral can control up to an 8x8 matrix key pad where all the
scanning is done via software. The hardware provides two interrupts:
one for key presses (KDI) and one for all key releases (KRI). There is
also a simple circuit for glitch reduction (said for synchronization)
made by two series of 3 D-latches clocked by the keypad-clock that
stabilize the interrupts sources. KDI and KRI are fired only if the
respective conditions are maintained for at last 4 keypad-clock cycle.
Since those circuits are poor for a correct debounce process (the
keypad-clock frequency is 32K and bounces longer than 94us are not
masked) the driver, when an interrupt arrives, samples the matrix
with a period of 10ms until the readins are stable for
IMX_KEYPAD_SCANS_FOR_STABILITY times (currently set at 3). After
getting stable result appropriate events are sent through the input
stack.
If some keys are maintained pressed, the driver continues to scan
the matrix with a longer period (60ms) to catch possible multiple
key presses without overloading the cpu. This process ends when all
keys are released.
This driver is tested to build in kernel or as a module and follow
the specification of Freescale Application processors:
i.MX25 i.MX27 i.MX31 i.MX35 i.MX51 especially tested on i.MX31.

Sometimes it is desirable to suppress certain events from reaching
input handlers and thus user space. One such example is Mac mouse
button emulation code which catches certain key presses and converts
them into button clicks as if they were emitted by a virtual mouse.
The original key press events should be completely suppressed,
otherwise user space will be confused, and while keyboard driver
does it on its own evdev is blissfully unaware of this arrangement.
This patch adds notion of 'filter' to the standard input handlers,
which may flag event as filtered thus preventing it from reaching
other input handlers. Filters don't (nor will they ever) have a
notion of priority relative to each other, input core will run all
of them first and any one of them may mark event as filtered.
This patch is inspired by similar patch by Matthew Garret but the
implementation and intended usage are quite different.

For configurations where Synaptics hardware is present but the Synaptics
extensions support is not compiled in, the mouse is reprobed and a new
device is allocated on every suspend/resume.
During probe, psmouse_switch_protocol() calls psmouse_extensions() with
set_properties=1. This calls the dummy synaptics_init() which returns an
error code, instructing us not to use the synaptics extensions.
During resume, psmouse_reconnect() calls psmouse_extensions() with
set_properties=0, in which case call to synaptics_init() is bypassed and
PSMOUSE_SYNAPTICS is returned. Since the result is different from previous
attempt psmouse_reconnect() fails and full re-probe happens.
Fix this by tweaking the set_properties=0 codepath in psmouse_extensions()
to be more careful about offering PSMOUSE_SYNAPTICS extensions.

When using realtime signals, we'll enqueue one signal for every event.
This is unfortunate, because (for example) keyboard presses are three
events: key, msc scancode, and syn. They'll be enqueued fast enough in
kernel space that all three events will be ready to read by the time
userspace runs, so the first invocation of the signal handler will read
all three events, but then the second two invocations still have to run
to do no work.
Instead, only send the SIGIO notification on syn events. This is a
slight abuse of SIGIO semantics, in principle it ought to fire as soon
as any events are readable. But it matches evdev semantics, which is
more important since SIGIO is rather vaguely defined to begin with.

S3C24XX touchscreen driver, originally written by Arnaud Patard and
other contributors. The driver has had substantial testing as well as
a number of tidying up passes done by Ben Dooks, as noted:
- added kernel-doc comments to most of the routines
- removed old code from pre adc framework days
- updated device probe code to use platform id list matching
- cleaned up debug, since printk() now has timestamp feature
- ensure code uses dev_() reporting macros where necessary
- remove ABS_PRESSURE reporting, tslib can be fixed
- ensure timer is removed on driver exit
- move to using dev_pmops for power management

OQO 01+ multimedia keys produce 6x on press, e0 6x upon release.
As a result, Linux thinks that another key has been pressed (or is
repeating), when it is actually a release of the same key. Mangle the
release scancode when running on OQO so that driver recognizes it as
such.
Since the device does not have external PS/2 ports mangling is safe
since there is no chance that an external keyboard is connected.

input_devices_seq_start() uses mutex_lock_interruptible() to acquire
the input_mutex, but doesn't properly handle the situation when the
call fails (for example due to interrupt). Instead of returning NULL
(which indicates that there is no more data) we should return
ERR_PTR()-encoded error.
We also need explicit flag indicating whether input_mutex was acquired
since input_devices_seq_stop() is called whether input_devices_seq_start()
was successful or not.
The same applies to input_handlers_seq_start().

We need to postpone restoring LED state and typematic settings until
keyboard is finished reconnecting upon resume. Normally driver core
and PM infrastructure takes care of proper ordering and dependencies,
but or case actual reconnect is done asynchronously from kseriod.
So while driver core thinks that keyboard was resumed and it is time
to let input core run it's resume handlers in reality keyboard is not
ready yet. The solution is to keep rescheduling work that adjusts LED
and rate settings until keyboard is fully enabled.

It happens because the new INPUT_WINBOND_CIR driver relies on new-leds

But it selects LEDS_CLASS, which confuses a number of other drivers into
thinking that all the leds infrastructure is in place.
Fix this by selecting NEW_LEDS as well, like similar drivers do.
Eventually, this whole leds infrastructure complexity should be
cleaned up, it's been going on for years.

This makes it consistent with other buses (platform, i2c, vio, ...). I'm
not sure why we use the prefixes, but there must be a reason.
This was easy enough to do it, and I did it.

This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.
This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.
Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

Ever since we switched from having a polling timer to registering IRQ
handlers for both keyboard and AUX ports at the driver registration
time, on certain boxes probing for a mouse results in keyboard
stopping working. The only real difference between old and new way is
that before we disabled ports after unsuccessful probe whereas now we
leave them as is. Try to emulate the old behavior by disabling and
immediately re-enabling AUX and KBD ports when corresponding serio
port is being closed.

It seems that many laptops do not fully implement AUX LOOP command in
their keyboard controllers, causing issues with touchpad detection.
We know however that almost every laptop/portable uses a PS/2 pointing
device and, even if user disables it in favor of an external mouse,
the system will not use IRQ 12 for anything else. Therefore we may
bypass AUX IRQ delivery test when running on a laptop and assume that
it is routed properly.
Just to be safe we require the box to have good PNP data in order to
bypass the test.
