eef3e4cab7 Input: add driver for Synaptics I2C touchpad
This driver supports Synaptics I2C touchpad controller on eXeda
mobile device. Unfortunaltely it only works in relative mode and
thus is not comaptible with Xorg Synaptics driver.

ec20a022aa Input: synaptics - add support for reporting x/y resolution
Synaptics uses anisotropic coordinate system.  On some wide touchpads
vertical resolution can be twice as high as horizontal which causes
unequal sensitivity on x/y directions.  Add support for reading the
resolution with EVIOCGABS ioctl.

08604bd993 time: move PIT_TICK_RATE to linux/timex.h
PIT_TICK_RATE is currently defined in four architectures, but in three
different places.  While linux/timex.h is not the perfect place for it, it
is still a reasonable replacement for those drivers that traditionally use
asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency.

Note that for Alpha, the actual value changed from 1193182UL to 1193180UL.
 This is unlikely to make a difference, and probably can only improve
accuracy.  There was a discussion on the correct value of CLOCK_TICK_RATE
a few years ago, after which every existing instance was getting changed
to 1193182.  According to the specification, it should be
1193181.818181...

1b713e0050 xen: remove driver_data direct access of struct device from more drivers
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

dc890c2dcd [ARM] 5544/1: Trust PrimeCell resource sizes
I found the PrimeCell/AMBA Bus drivers distrusting the resource
passed in as part of the struct amba_device abstraction. This
patch removes all hard coded resource sizes found in the PrimeCell
drivers and move the responsibility of this definition back to
the platform/board device definition, which already exist and
appear to be correct for all in-tree users of these drivers.
We do this using the resource_size() inline function which was
also replicated in the only driver using the resource size, so
that has been changed too. The KMI_SIZE was left in kmi.h in case
someone likes it. Test-compiled against Versatile and Integrator
defconfigs, seems to work but I don't posess these boards and
cannot test them.

Some SoCs support only pin change interrupts on GPIO pins used as irq
lines.

The ads7846 core is not affected from the additional irqs on the rising
edge because the code accounts touch bounce anyway by kicking in a timer
and disabling the irq after the first request and reenabling the irq after
a timeout when there is no longer pen down detected.

7e3f73754e Input: add support for touchscreen on W90P910 ARM platform
The touchscreen works in two modes, wait trigger mode and auto-semi
mode. The device starts in wait trigger mode and waits until pressure
is detected, then device sets WT_INT bit and raises an interrupt.
The driver should put the device into auto-semi mode and prepare for
reading first X and then Y coordinates. When coordinate data is ready
the driver sets ADC_INT bit and raises interrupt again.

Jeremy Huddleston
05e882f890 Input: appletouch - improve finger detection
The appletouch driver is prone to reporting multiple fingers when only
one is pressing.  The appletouch driver queries an array of pressure
sensors and counts local maxima in pressure to determine the number of
fingers.  It just does this on the raw values, so a data stream like:

0 100 250 300 299 300 250 100 0

actually registers as 2 fingers.

This patch updates the logic to ignore small dips in pressure that are
less than the threshold.

get scheduled till much later and we erroneously decide that
device timed out. Work around this problem by checking whether we

AA instead of AA 00, the psmouse-base code handles the case of AA 00 by

9b771ac442 Input: lifebook - don't send incomplete events
When we get a relative packet from trackpoint (when we deal with
touchscreen/trackpoint combo) we should not send events for the device
corresponding to touchscreen as it confuses evtouch driver (it looks
like it keeps previously reported absolute coordinates and the cursor
stays in the same place).

9e68177ef9 Input: ff-memless - fix signed to unsigned bit overflow
When userspace sets effect->u.rumble.strong_magnitude to 0x8001 or
larger, ml_combine_effects() would always return strong_magnitude
0xffff.

Problem is that 'gain' is passed in as signed integer. Multiplying
magnitude (__u16) with gain (int) causes magnitude read as signed and
results negative value (with magnitude > 0x8000). This signed integer
is then divided and value, still negative, converted to 32bit unsigned
integer. Finally checking combine overflow min(new+old, 0xffff) gives
out 0xffff.

Fix is to simply change 'gain' to unsigned int.

d07a9cba6b Input: joydev - blacklist digitizers
BTN_TOUCH is not set by the wacom driver which causes it to be handled by the
joydev driver while the resulting device is broken. This causes problems with
applications that try to use a joystick device.

84e5b0d00f Input: wm97xx - do not access dev->driver_data directly
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

5e5ee686e3 Input: add detailed multi-touch finger data report protocol
In order to utilize the full power of the new multi-touch devices, a
way to report detailed finger data to user space is needed. This patch
adds a multi-touch (MT) protocol which allows drivers to report details
for an arbitrary number of fingers.

The driver sends a SYN_MT_REPORT event via the input_mt_sync() function
when a complete finger has been reported.

In order to stay compatible with existing applications, the data
reported in a finger packet must not be recognized as single-touch
events. In addition, all finger data must bypass input filtering,
since subsequent events of the same type refer to different fingers.

A set of ABS_MT events with the desired properties are defined. The
events are divided into categories, to allow for partial implementation.
The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked.
If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide
the size of the approaching finger. Anisotropy and direction may be
specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and
ABS_MT_ORIENTATION. Devices with more granular information may specify
general shapes as blobs, i.e., as a sequence of rectangular shapes
grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE
may be used to specify whether the touching tool is a finger or a pen.

61994a61bc Input: allow certain EV_ABS events to bypass all filtering
With the upcoming multi-touch interface as an example, there is
a need to make certain that all reported events actually get passed
to the event handler. This patch equips the input core with the
ability to bypass all filtering for certain EV_ABS events.
