From 278d72ae8803ffcd16070c95fe1d53f4466dc741 Mon Sep 17 00:00:00 2001 From: Max Asbock Date: Tue, 21 Jun 2005 17:16:34 -0700 Subject: [PATCH] ibmasm driver: redesign handling of remote control events This patch rewrites the handling of remote control events. Rather than making them available from a special file in the ibmasmfs, now the events from the RSA card get translated into kernel input events and injected into the input subsystem. The driver now will generate two /dev/input/eventX nodes -- one for the keyboard and one for the mouse. The mouse node generates absolute events more like a touch pad than a mouse.
