e42b6646a8 Input: synaptics - report multi-taps only if supported by the device
According to Section 2.4.4 of the Synaptics TouchPad Interfacing
Guide, bit 2 specifies if multi-finger detection is provided by
the touchpad. Thus, only set BTN_TOOL_DOUBLETAP and
BTN_TOOL_TRIPLETAP if the device actually supports it.

09779678d1 Input: appletouch - driver refactoring
The appletouch driver has grown up from supporting only a couple of
touchpads into supporting many touchpads, which can have different
number of sensors, different aspect ratios etc.

This patch cleans up the current driver code and makes it easy to
support the features of each different touchpad.

As a side effect, this patch also modifies the 'Y' multiplication factor
of the 'geyser3' and 'geyser4' touchpads (found on Core Duo and Core2
Duo MacBook and MacBook Pro laptops) in order to make the touchpad
output match the aspect ratio of the touchpad (Y factor changed from 43
to 64).

2a0bd75e5e Input: psmouse - add support for Elantech touchpads
This is version 5 of the driver. Relative mode support has been
dropped (users wishing to use touchpad in relative mode can use
standard PS/2 protocol emulation done in hardware). The driver
supports both original version of Elantech protocol and the newer
one used by touchpads installed in EeePC.

df08ef27a7 Input: psmouse - add OLPC touchpad driver
This adds support for OLPC's touchpad.  It has lots of neat features,
none of which are enabled because the hardware is too buggy.  Instead,
we use it like a normal touchpad, but with a number of workarounds in
place to deal with the frequent hardware spasms.  Humidity changes,
sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All
tend to cause the touchpad to freak out.

We want to support attr->set callbacks that may need psmouse->state to
not be updated, or may want to manually deal w/ enabling and disabling
the device.  To do that, we create __PSMOUSE_DEFINE_ATTR which enables
us to set a 'protect' argument specifying whether or not the set
callback should be protected with psmouse_disable and state setting.

psmouse_queue_work is passed a delayed_work struct, and queues up the work
with kpsmouse_wq.  Since we're dealing with delayed_work stuff, this
also switches resync_work to a delayed_work struct as well, and makes
use of psmouse_queue_work when doing a resync within psmouse-base.

cd72ad3f57 Input: bcm5974 - switch back to normal mode when closing
Staying in multi-touch mode after closing the device sometimes makes
the keyboard drop keys or repeat keys irratically. The conjecture is
that some internal buffer starts to overflow, resulting in undefined
behavior. Switching back to normal mode when closing the device makes
the problem go away.

75e21e3f3b Input: bcm5974 - improve finger tracking and counting
The problem of finger tracking, i.e., when to switch focus from one
finger to another on the trackpad, has been improved by utilizing more
information from the bcm5974 chip output. This results in less pointer
hopping when many fingers are on the trackpad. In addition, a finger
counting method based on pressure information from all fingers is
introduced. Together with a pressure hysteresis window, this yields a
more stable counting of the number of fingers on the trackpad.
