Input: mt - document devices reporting more touches than slots

2011-08-24T06:08:20Z

Some devices are capable of identifying and/or tracking more contacts than they can report to the driver. Document how a driver should handle this, and what userspace should expect. Signed-off-by: Daniel Kurtz Acked-by: Chase Douglas Acked-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

input: mt: Add hovering distance axis

2010-12-16T09:42:29Z

Touch devices capable of hovering, i.e., fingers detected a distance from the surface, are not supported by the current input MT protocol. This patch adds ABS_MT_DISTANCE, which may be used to indicate the distance between the contact and the surface. Signed-off-by: Henrik Rydberg

2010-07-16T06:52:10Z

This patch adds documentation for the ABS_MT_SLOT event and gives examples of how to use the event slot protocol. Reviewed-by: Ping Cheng Signed-off-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: update the status of the Multitouch X driver project

2010-03-22T05:39:33Z

The Multitouch X driver project has moved to alpha status. This patch updates the documentation accordingly. Signed-off-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: clarify the no-finger event in multitouch protocol

2010-03-22T05:38:56Z

The current documentation does not explicitly specify how to report zero fingers, leaving a potential problem in the driver implementations and giving no parsing directive to userland. This patch defines two equally valid ways. Signed-off-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

2010-01-29T06:32:52Z
