From 58fb021827b7455e05d89371556e6c255e9fb2e1 Mon Sep 17 00:00:00 2001 From: Chris Bagwell Date: Mon, 19 Jul 2010 09:06:15 -0700 Subject: Input: synaptics - set min/max for finger width Reporting this will allow GUI config apps to correctly scale width sensitive config values (such as palm detect) to correct range. Current user apps are detecting kernels min/max=0/0 and making an assumption that it means 0/16 or 0/15. Synaptics touchpad interface guides show 4/15 are correct values but driver forces to 0 when no fingers on touchpad.
