8b86c1c28f Input: atmel_mxt_ts - convert to MT protocol B
Atmel touchscreen chips can use MT protocol B because they can assign
unique id to ABS_MT_TRACKING_ID from finger id provided by hardware.

4203306506 Input: add driver for Maxim max11801 touchscreen controller
Add MAXI max11801 resistive touchscreen controller driver. This driver
uses Auto Mode and Aperture Mode.

Support for other max1180x devices can be added to this driver as well,
as they use almost the same register addresses and codes.

5cb81d19ba Input: tsc2005 - remove 'disable' sysfs attribute
I believe that enable/disable functionality should not be implemented on
the individual driver level but rather in device core, potentially
reusing parts of PM framework. Therefore the driver-specific "disable"
attribute is removed from the mainline driver.

0b950d3d7c Input: tsc2005 - add open/close
Introduce open and close methods for the input device to keep the device
powered down when it is not in use. Also rework interaction between
interrupt thread and starting/shutting off/resetting the device: instead
of taking a mutex in the intterrupt thread and elsewhere disable interrupts
before transitioning the device in a new state.

The ESD handling is also separated from the IRQ thread; we poll regularly
at a given interval and simply skip reads if we see that valid interrupt
happened not so long ago. This allows us not cancel and reschedule ESD
work from interrupt context all the time.

8c3c283e6b Input: xen-kbdfront - advertise either absolute or relative coordinates
A virtualized display device is usually viewed with the vncviewer
application, either by 'xm vnc domU' or with vncviewer localhost:port.
vncviewer and the RFB protocol provides absolute coordinates to the
virtual display. These coordinates are either passed through to a PV
guest or converted to relative coordinates for a HVM guest.

A PV guest receives these coordinates and passes them to the kernels
evdev driver. There it can be picked up by applications such as the
xorg-input drivers. Using absolute coordinates avoids issues such as
guest mouse pointer not tracking host mouse pointer due to wrong mouse
acceleration settings in the guests X display.

Advertise either absolute or relative coordinates to the input system
and the evdev driver, depending on what dom0 provides. The xorg-input
driver prefers relative coordinates even if a devices provides both.

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.
