Input: wacom - add POINTER and DIRECT device properties

2011-09-08T16:42:28+00:00

Adds INPUT_PROP_POINTER or INPUT_PROP_DIRECT as necessary to the
hardware supported by the Wacom driver. The DIRECT property is
assigned to devices with an embedded screen (i.e. touchscreens
and display tablets). The POINTER property is assigned to those
without embedded screens.

Input: wacom_w8001 - simplify w8001_remove

2011-08-24T06:07:51+00:00

Since touchscreen driver does not handle any events to be sent to the
device we can close serio port first and then unregister the input device.

Input: wacom_w8001 - implement open and close

2011-08-24T06:07:47+00:00

Implement open() and close() methods for the input device so that we
do not start the device unless there are users listening to the events.

Input: wacom_w8001 - report resolution to userland

2011-02-01T05:32:24+00:00

Serial devices send both pen and touch data through the same logical
port. Since we scaled touch to pen maximum, we use pen resolution
for touch as well here.

This is under the assumption that pen and touch share the same physical
surface. In the case when a small physical dimensional difference occurs
between pen and touch, we assume the tolerance for touch point precision
is higher than pen and the difference is within touch point tolerance.

A per-MT tool based resolution mechanism should be introduced if the
above assumption does not hold true for the pen and touch devices any
more.

Input: wacom_w8001 - add single-touch support

2011-01-11T09:07:44+00:00

Emulate single-touch compatible events for the 2-finger panels
so that they can be used with single-touch legacy clients.

Assign device ids as Wacom USB vendor ID and product ID.
Name the device to reflect its specific features.

Scale touch coordinates to pen maximum if pen supported.

Input: wacom_w8001 - support pen or touch only devices

2010-12-30T08:23:10+00:00

Not all penabled devices support touch. The same holds true for touch
devices, so we should be setting up devices according to the results
returned when we query the hardware.

input: mt: Move tracking and pointer emulation to input-mt

2010-12-16T09:41:38+00:00

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver.  This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.

input: mt: Collect slots initialization code

2010-12-16T09:41:12+00:00

The MT slots devices all follow the same initialization pattern
of creating slots and hinting about buffer size. Let drivers call
an initialization function instead, and make sure it can be called
repeatedly without side effects.
