From d297b9bdad044a732223b44c19e8223d93fd3aa0 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 3 Jul 2012 11:21:28 +0200 Subject: [PATCH] staging iio adt7410: make 16bit mode default In 13bit mode the lower three bits of the adc value contain flags. The driver does not use these flags at all, so make 16bit mode the default.
