a43c7c5383 Input: wacom - support one finger touch the touchscreen way
There are two types of 1FGT devices supported in wacom_wac.c.
Changing them to follow the existing touchscreen format, i.e.,
only report BTN_TOUCH as a valid tool type.

Touch data will be ignored if pen is in proximity. This requires
a touch up event sent if touch was down when pen comes in. The
touch up event should be sent before any pen events are emitted.
Otherwise, two pointers would race for the cursor.

However, we can not send a touch up inside wacom_tpc_pen since
pen and touch are on different logical port. That is why we
have to check if touch is up before sending pen events.

As was recently brought up on the busybox list
(http://lists.busybox.net/pipermail/busybox/2011-January/074565.html),
evdev_write doesn't properly check the count argument, which will
lead to a return value > count on partial writes if the remaining bytes
are accessible - causing userspace confusion.

Fix it by only handling each full input_event structure and return -EINVAL
if less than 1 struct was written, similar to how it is done in evdev_read.

0d3c07378b Input: atmel_mxt_ts - remove matrix size check
The mxt_check_matrix_size() is currently setting the CTE mode to match
xline/yline information that is in the platform data, but it does not
take into account for example the fact that we could have a key array
in use too (key array would use some x/y lines as well).

It would be better to simply rely on the configuration data, and make
sure that the CTE mode set in there matches the touch object (touchscreen,
key array, proximity) configuration (which are set in the config data too).

1d64b655dc Input: serio/gameport - use 'long' system workqueue
Commit 8ee294cd9d converted serio
subsystem event handling from using a dedicated thread to using
common workqueue. Unfortunately, this regressed our boot times,
due to the fact that serio jobs take long time to execute. While
the new concurrency managed workqueue code manages long-playing
works just fine and schedules additional workers as needed, such
works wreck havoc among remaining users of flush_scheduled_work().

To solve this problem let's move serio/gameport works from system_wq
to system_long_wq which nobody tries to flush.

Apparently there exist userspace programs that expect to be able to
"loop back" and distribute to readers events written into

handler broke them. Now that SysRq uses alternative method to suppress
filtering of the events it re-injects we can safely revert this change.

19e9554153 Input: serio - clear pending rescans after sysfs driver rebind
When rebinding a serio driver via sysfs drvctl interface it is
possible for an interrupt to trigger after the disconnect of the
existing driver and before the binding of the new driver.  This will
cause the serio interrupt handler to queue a rescan event which will
disconnect the new driver immediately after it is attached.

This change removes pending rescans from the serio event queue after
processing the drvctl request but before releasing the serio mutex.

Reproduction involves issuing a rebind of device port from psmouse
driver to serio_raw driver while generating input to trigger
interrupts.  Then checking to see if the corresponding
i8042/serio4/driver is correctly attached to the serio_raw driver
instead of psmouse.

Ping Cheng
28a1bc1c0a Input: wacom_w8001 - report resolution to userland
Serial devices send both pen and touch data through the same logical
port. Since we scaled touch to pen maximum, we use pen resolution
for touch as well here.

This is under the assumption that pen and touch share the same physical
surface. In the case when a small physical dimensional difference occurs
between pen and touch, we assume the tolerance for touch point precision
is higher than pen and the difference is within touch point tolerance.

A per-MT tool based resolution mechanism should be introduced if the
above assumption does not hold true for the pen and touch devices any
more.

Platform data is supported to allow configuration of system parameters such
as selection between four and five wire touchscreens and for specification
of optional direct to CPU IRQs for sample availability and for pen down.
Use of this feature for at least the data IRQ is strongly recommended.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

sends a final main packet with x == 1. Since the normal values are above

fec6e5252b Input: synaptics - add multi-finger and semi-mt support
The Synaptics 2.7 series of touchpads support a mode for reporting two
sets of X/Y/Pressure data (advanced gesture mode). By default, these
devices report only single finger data, depriving userspace of the
nowadays ubiquitous two-finger scroll gesture.

Enabling advanced gesture mode also enables the multi-finger report,
although the device does not claim that capability. Up to three
fingers can be reported this way.

While two or three fingers are touching, the normal packet is
prepended by a reduced finger packet of lower resolution. From the two
packets (which do not represent the actual fingers), the bounding
rectangle of the individual contacts can be extracted.  This
information is sufficient to perform scaling gestures and a limited
form of rotation gesture. The behavior has been coined semi-mt
capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT
device property.

Work to decode the advanced gesture packet: Takashi Iwai.
Cleanup and testing of the original patch: Chase Douglas.
Minor cleanup and testing: Chris Bagwell.
Finalization and semi-mt support: Henrik Rydberg.

85b7720039 Input: introduce device properties
Today, userspace sets up an input device based on the data it emits.
This is not always enough; a tablet and a touchscreen may emit exactly
the same data, for instance, but the former should be set up with a
pointer whereas the latter does not need to. Recently, a new type of
touchpad has emerged where the buttons are under the pad, which
changes logic without changing the emitted data. This patch introduces
a new ioctl, EVIOCGPROP, which enables user access to a set of device
properties useful during setup. The properties are given as a bitmap
in the same fashion as the event types, and are also made available
via sysfs, uevent and /proc/bus/input/devices.

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver.  This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.

ab4e019219 Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2
The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while
extending them to support large scancodes was a mistake. While we tried
to keep ABI intact (and we succeeded in doing that, programs compiled
on older kernels will work on newer ones) there is still a problem with
recompiling existing software with newer kernel headers.

New kernel headers will supply updated ioctl numbers and kernel will
expect that userspace will use struct input_keymap_entry to set and
retrieve keymap data. But since the names of ioctls are still the same
userspace will happily compile even if not adjusted to make use of the
new structure and will start miraculously fail in the field.

To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions
and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly
select the style of ioctls it wants to employ.

In 0xc0-cap response, the 1-button ClickPad has the 20-bit set while
2-button ClickPad has the 8-bit set.

This patch makes the kernel only handle 1-button ClickPad specially,

39de52104d Input: serio HIL MLC - don't deref null, don't leak and return proper error
While reviewing various users of kernel memory allocation functions I came
across drivers/input/serio/hil_mlc.c::hil_mlc_register() and noticed that:

 - it calls kzalloc() but fails to check for a NULL return before use.
 - it makes several allocations and if one fails it doesn't free the
   previous ones.
 - It doesn't return -ENOMEM in the failed memory allocation case (it just
   crashes).

This patch corrects all of the above and also reworks the only caller of
this function that I could find
(drivers/input/serio/hp_sdc_mlc.c::hp_sdc_mlc_out()) so that it now checks
the return value of hil_mlc_register() and properly propagates it on
failure and I also restructured the code to remove some labels and goto's
to make it, IMHO nicer to read.

c0dc834265 Input: hgpk - rework spew detection
The old implementation of spew detection simply tracked the overall
position delta of the cursor over every 100 packets. We found that
this causes occasional false positives in spew detection, and also
that the conditions of the spewy packets are perhaps more fixed than
we once thought.

Rework the spew detection to look for packets of specific small
delta, and only recalibrating if the overall movement delta stays
within expected bounds.

Also discard duplicate packets in the advanced mode, which appear
to be very common. If we don't, the spew detection kicks in far
too early. If we get a large spew of duplicates, request a
recalibration straight up.

Add a "hgpk_mode" sysfs attribute that allows selection between 3 options:
Mouse (the existing option), GlideSensor and PenTablet.

GlideSensor is an enhanced protocol for the regular touchpad mode that
additionally reports pressure and uses absolute coordinates. We suspect
that it may be more reliable than mouse mode in some environments.

PenTablet mode puts the touchpad into resistive mode, you must then use
a stylus as an input. We suspect this is the most reliable way to drive
the touchpad.

The GlideSensor and PenTablet devices expose themselves with the
intention of being combined with the synaptics X11 input driver.

5fdbe44d03 Input: do not pass injected events back to the originating handler
Sometimes input handlers (as opposed to input devices) have a need to
inject (or re-inject) events back into input core. For example sysrq
filter may want to inject previously suppressed Alt-SysRq so that user
can take a screen print. In this case we do not want to pass such events
back to the same same handler that injected them to avoid loops.

17d01f28e1 Input: pcf8574_keypad - fix error handling in pcf8574_kp_probe
It is not allowed to call input_free_device() after calling
input_unregister_device() because input devices are refcounted and
unregister will free the device if we were holding he last referenc.

The preferred style in input/ is to make input_register_device() the
last function in the probe which can fail.  That way we don't need to
call input_unregister_device().

Also do not need to call input_set_drvdata() as nothing in the driver
uses the data.

8c5188b6d3 Input: atkbd - add 'terminal' parameter for IBM Terminal keyboards
Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate
using a protocol similar, but not identical to the AT keyboard protocol.
(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and
possibly others.)

When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they
can be connected to a standard PC, with three caveats:

a) They can only use scancode set 3; requests to use anything else are
quietly ignored.
b) The AT Command to request Make, Break and Repeat codes is not properly
interpreted.
c) The top function keys on a 122 key keyboard, and the arrow/edit keys in
the middle of the board send non-standard scancodes.

C) is easily taken care of in userspace, by use of setkeycodes
B) can be taken care of by a userspace hack (that makes the kernel complain
in dmesg)
A) is fixable in theory, but on the keyboard i tested on (6110668), it seems
to be detected unoverridably as Set 2, causing userspace oddities that make
it harder to fix C).

Enclosed is a small patch to the kernel that fixes A) and B) in the kernel,
making it much easier to fix C) in userspace. It adds a single kernel
command line parameter that overrides the detection that sets these boards
as set 2, and instead of sending the Make-break-repeat command to the
keyboard, it sends the make-break command, which is properly recognized by
these keyboards. Software level key repeating seems to make up for the lack
of hardware repeat codes perfectly.

Without manually setting the command line parameter (tentatively named
atkbd.terminal), this code has no effect, and the driver works exactly as
before.

The Sony VPCZ1 doesn't support active multiplexing and trying to enable
it causes keyboard to stop working. Since most (all?) VAIOs do not have
external PS/2 ports nor they implement active multiplexing properly, and
trying to enable MUX usually messes up keyboard/touchpad, let's simply
disable MUX probing based on board name (VAIO).

KGDB, much like the resume process, needs to be able to mark all keys that
were pressed at the time we dropped into the debuggers as "released", since
it is unlikely that the keys stay pressed for the entire duration of the
debug session.

Also we need to make sure that input_reset_device() and input_dev_suspend()
only attempt to change state of currenlt opened devices since closed devices
may not be ready to accept IO requests.

b584efc9ea Input: ad7879 - prevent invalid finger data reports
Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.

The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.

Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.

We also reject samples where pressure is greater than pressure_max.

2991a1ca6e Input: ads7846 - switch to using threaded IRQ
Commit 9114337 introduces regulator operations in ads7846 touchscreen
driver. Among these operations, some are called while holding a
spinlock. On many platforms regulators reside on slow buses, such as
I2C/SPI and require sleep while accessing them.

The touchscreen itself is also a SPI device and currently relies on
asynchronous SPI access to avoid sleeping in interrupt context. Let's
switch to using threaded IRQ to be able to access SPI bus
synchronously (which simplifies driver a bit); it also allows safe
access to the regulators as well.

This has been tested on the ti_omap3530evm board:
 1) using ts_lib after normal boot
 2) using ts_lib after "#echo 1/0 > /sys/bus/spi/devices/spi0.1/disable"
 3) using ts_lib after "#echo mem > /sys/power/state" and "wake up"

Also tested on pandora.

6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

This allows keyboard to wake-up OMAP from suspend.

613655fa39 drivers: autoconvert trivial BKL users to private mutex
All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

These drivers do not seem to be under active
maintainance from my brief investigation. Apologies
to those maintainers that I have missed.

name=$2
if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
            sed -i '/include.*<linux\/smp_lock.h>/d' ${file}

f6cd378372 Input: wacom - fix runtime PM related deadlock
When runtime PM is enabled by default for input devices, X hangs in

[<ffffffffa02bc94b>] wacom_resume+0x3b/0x90 [wacom]

[<ffffffff81328176>] usb_autopm_get_interface+0x26/0x60
[<ffffffffa02bc626>] wacom_open+0x36/0x90 [wacom]

wacom_open() takes wacom->lock and calls usb_autopm_get_interface(),
which in turn calls wacom_resume() which tries to acquire the lock
again.

The fix is to call usb_autopm_get_interface() first, before we take
the lock.

Since we do not do usb_autopm_put_interface() until wacom_close()
is called runtime PM is effectively disabled for the driver, however
changing it now would risk regressions so the complete fix will
have to wait till the next merge window.
