Dmitry Torokhov 0d87c7228a Input: adp5588-keypad - fix NULL dereference in adp5588_gpio_add()
The kpad structure is assigned to i2c client via i2s_set_clientdata()
at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to
access it (via dev_get_drvdata! which is not nice at all) causing an
oops.

Let's pass pointer to kpad directly into adp5588_gpio_add() and
adp5588_gpio_remove() to avoid accessing driver data before it is
set up.

Also split out building of gpiomap into a separate function to
clear the logic.

These are a couple smatch issues.  In the original code, if only one of

Dmitry Torokhov 1ca56e513a Input: i8042 - reset keyboard controller wehen resuming from S2R
Some laptops, such as Lenovo 3000 N100, require keyboard controller reset
in order to have touchpad operable after suspend to RAM. Even if box does
not need the reset it should be safe to do so, so instead of chasing
after misbehaving boxes and grow DMI tables, let's reset the controller
unconditionally.

Dmitry Torokhov 3fea60261e Input: twl40300-keypad - fix handling of "all ground" rows
The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c)
defines a key map for the matrix keypad keyboard. The hardware seems to
use all of the 8 rows and 8 columns of the keypad, although not all
possible locations are used.

The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys
are defined with a row and column number between 0 and 7, except

        KEY(0xff, 2, KEY_F9),
        KEY(0xff, 4, KEY_F10),
        KEY(0xff, 5, KEY_F11),

which represent keycodes that should be emitted when entire row is
connected to the ground.  since the driver handles this case as if we
had an extra column in the key matrix. Unfortunately we do not allocate
enough space and end up owerwriting some random memory.

Chris Bagwell 58fb021827 Input: synaptics - set min/max for finger width
Reporting this will allow GUI config apps to correctly scale
width sensitive config values (such as palm detect) to correct
range.  Current user apps are detecting kernels min/max=0/0 and
making an assumption that it means 0/16 or 0/15.

Synaptics touchpad interface guides show 4/15 are correct values
but driver forces to 0 when no fingers on touchpad.

Chris Bagwell 2a8e77102e Input: synaptics - only report width on hardware that supports it
Synaptics devices report fixed value of 5 for finger/palm widths
on devices that do not support capability and driver further
hardcodes to 5.  Stop reporting this fixed value when its not
supported since its not useful.

This will aid applications so they can better auto-enable support
for multi-touch emulation and palm detection logic using finger
width only for devices that support width detection.

I can find no applications that currently require existence on
ABS_TOOL_WIDTH. Since only synaptics and bcm input devices
currently support this tool, it seems they must handle it
gracefully.

Henrik Rydberg 40d007e7df Input: introduce MT event slots
With the rapidly increasing number of intelligent multi-contact and
multi-user devices, the need to send digested, filtered information
from a set of different sources within the same device is imminent.
This patch adds the concept of slots to the MT protocol. The slots
enumerate a set of identified sources, such that all MT events
can be passed independently and selectively per identified source.

The protocol works like this: Instead of sending a SYN_MT_REPORT
event immediately after the contact data, one sends an ABS_MT_SLOT
event immediately before the contact data. The input core will only
emit events for slots with modified MT events. It is assumed that
the same slot is used for the duration of an initiated contact.

Christoph Fritz 7beae7028a Input: xpad - remove mouse buttons and axes for dance pads
Dance pads don't have any axes/sticks, only buttons for directions. For
example buttons like left+right will get triggered at once, an axis
can't handle this anyway.  So this patch adds a module parameter named
"sticks_to_null" for unknown devices. A known dance pad makes use of
it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other
tested devices may follow by adding this mapping-option too.

Some buttons of xpad-devices are addressing mouse-buttons instead of
gamepad-buttons. This gets fixed too.

Anatolij Gustschin 3eac5c7e44 Input: ads7846 - extend the driver for ads7845 controller support
ADS7845 is a controller for 5-wire touch screens and somewhat
different from 7846. It requires three serial communications to
accomplish one complete conversion. Unlike 7846 it doesn't allow
Z1-/Z2- position measurement.

The patch extends the ads7846 driver to also support ads7845.
The packet struct is extended to contain needed command and
conversion buffers. ads7846_rx() and ads7846_rx_val() now
differentiate between 7845 and 7846 case. ads7846_probe() is
modified to setup ads7845 specific command and conversion
messages and to switch ads7845 into power-down mode, since
this is needed to be prepared to respond to pendown interrupts.

Michael Hennerich 963ce8ae6d Input: ad7879 - report EV_KEY/BTN_TOUCH events

Implement EV_KEY/BTN_TOUCH and make sure that the release event
is not erroneous scheduled without a preceding valid touch.
Avoid duplicated BTN_TOUCH events, even though input core filters
them.
