drivers/input/keyboard/Kconfig defines QT2160 while the corresponding
Makefile expects CONFIG_KEYBOARD_QT2160 as all other keyboard drivers
do. To keep this Makefile consistent rename the config-token from
CONFIG_QT2160 to CONFIG_KEYBOARD_QT2160.
The various defconfig files are left alone.

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.

The commit 83ba9ea8a04b72dfee2515428c15e7414ba4fc61 ommitted the return
line for the old synaptics model accidentally. This resulted in a wrong

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.

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.

This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure. The reason
for this change is to unify the struct of_device definition amongst
all the architectures. It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.
A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).
This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device. After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.
This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.

A column or row configured as a GPI can be programmed to be part
of the key event table and therefore also capable of generating a
key event interrupt. A key event interrupt caused by a GPI follows
the same process flow as a key event interrupt caused by a key
press. GPIs configured as part of the key event table allow single
key switches and other GPI interrupts to be monitored. As part of
the event table, GPIs are represented by the decimal value 97 (0x61
or 1100001) through the decimal value 114 (0x72 or 1110010). See
table below for GPI event number assignments for rows and columns.
GPI Event Number Assignments for Rows
Row0 Row1 Row2 Row3 Row4 Row5 Row6 Row7
97 98 99 100 101 102 103 104
GPI Event Number Assignments for Cols
Col0 Col1 Col2 Col3 Col4 Col5 Col6 Col7 Col8 Col9

When the client buffer is very small and wraps around a lot, it may
well be that a write increases the head such that head == tail. If
this happens between the point where a poll is triggered and the
actual data is being read, there will be no data to read. This is
confusing to applications, which might end up closing the file.
This patch solves the problem by making sure the client buffer is
never empty after writing to it.

Some devices, in particular MT devices, produce a lot of data. This
may lead to overflowing of the event queues in evdev driver, which
by default are fairly small. Let the drivers hint the average number
of events per packet generated by the device, and use that information
when computing the buffer size evdev should use for the device.
