From 461a791765da501f73e3d5957788267101e800d2 Mon Sep 17 00:00:00 2001 From: JJ Ding Date: Fri, 9 Sep 2011 10:22:58 -0700 Subject: [PATCH] Input: elantech - get rid of ETP_2FT_* in elantech.h MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For two finger touches the coordinate of each finger gets reported separately but with reduced resolution. With this change, we now have the same range for ST and MT data and scale MT data because it has lower resolution to match ST.
