From 64528d03d7233800ec77f1acb9222cf090f926ca Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Wed, 30 Oct 2013 22:48:00 +0000 Subject: [PATCH] iio: hid-sensors: accelerometer: 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 accelerometer fields, which is most commonly used in currently available sensor hubs.
