From 2461fc9f3f45828eee23dd5018e7b5576aceec80 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Wed, 6 Nov 2013 00:11:00 +0000 Subject: [PATCH] iio: hid-sensors: magnetometer : Add sensitivity A number of Properties that can be applied to Data Fields are per data field basis or for all data fields. Adding sensitivity field for all magnetometer fields, which is most commonly used in currently available sensor hubs.
