From 7beae7028acec3bb235fa079fd7e45cc289c0fd7 Mon Sep 17 00:00:00 2001 From: Christoph Fritz Date: Tue, 13 Jul 2010 09:42:33 -0700 Subject: Input: xpad - remove mouse buttons and axes for dance pads Dance pads don't have any axes/sticks, only buttons for directions. For example buttons like left+right will get triggered at once, an axis can't handle this anyway. So this patch adds a module parameter named "sticks_to_null" for unknown devices. A known dance pad makes use of it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other tested devices may follow by adding this mapping-option too. Some buttons of xpad-devices are addressing mouse-buttons instead of gamepad-buttons. This gets fixed too.
