From 2a0bd75e5e687a9c34921e942c18477ea7ec2d63 Mon Sep 17 00:00:00 2001 From: Arjan Opmeer Date: Thu, 16 Oct 2008 22:10:19 -0400 Subject: Input: psmouse - add support for Elantech touchpads This is version 5 of the driver. Relative mode support has been dropped (users wishing to use touchpad in relative mode can use standard PS/2 protocol emulation done in hardware). The driver supports both original version of Elantech protocol and the newer one used by touchpads installed in EeePC.
