2011-08-23Input: add BTN_TOOL_QUINTTAP for reporting 5 fingers on touchpadDaniel Kurtz
"4-finger scroll" is a gesture supported by some applications and operating systems. "Resting thumb" is when a clickpad user rests a finger (e.g., a thumb), in a "click zone" (typically the bottom of the touchpad) in anticipation of click+move=select gestures. Thus, "4-finger scroll + resting thumb" is a 5-finger gesture. To allow userspace to detect this gesture, we send BTN_TOOL_QUINTTAP.

2010-12-16input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg
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.

2010-12-16input: mt: Collect slots initialization codeHenrik Rydberg
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. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
2010-12-16input: mt: Break out slots handlingHenrik Rydberg
In preparation for common code to handle a larger set of MT slots devices, move the slots handling over to a separate file. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
