From be26d664de1a6333156bd586a2f795271cfcf170 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 2 Dec 2009 19:54:31 +0100 Subject: mfd: Don't set mc13783 ADREFMODE for touch conversions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Setting ADREFMODE is utter nonsense, but that's hard to read out of the spec. Strange enough it's possible to read x and y values even when it's set. When unset you can get values not only for the axes, but also for contact resistance which allows the touch driver to report pressure values.
