-Subject: [PATCH] : lis302dl-configure-duration.patch
-
-Allow configuration of the duration for thresholds
-
-From: Simon Kagstrom <simon.kagstrom@gmail.com>
-
-This patch allows the configuration of duration used when generating
-filtered data (see the lis302dl application note). Also set a flag when
-the DR bit in the ctrl1 register is set to change the data rate and
-simplify the ms_to_duration utility functions.
-
-The sysfs 'duration' file is used for this.
