The OLPC XO laptop incorporates a combination touchpad/tablet device which unfortunately requires frequent recalibration. The driver will force this automatically when various suspicious behaviors are observed, and the user can recalibrate manually (with a special keyboard sequence). There's currently no way, however, for an external program to cause recalibration. We can not use the reconnect capability which is already available in /sys because full reset of the touchpad takes 1.1 - 1.2 secons which is too long. This patch creates a new node in /sys which, when written with '1', will force a touchpad recalibration; no other writes (or reads) of this node are supported.
