+Subject: [PATCH] : Acceleration threshold configuration: lis302dl-configure-threshold-on-bitbang.patch
+
+Configure threshold for accelerometer input
+
+From: Simon Kagstrom <simon.kagstrom@gmail.com>
+
+This patch, based on bitbang-all-the-way from the andy branch,
+implements a configurable acceleration threshold that need to be
+exceeded for the accelerometer to generate input data. The threshold can
+be set in sysfs:
+
+   cd /sys/devices/.../lis302dl.1/
+   echo 10 > threshold
+
+A value of 10 (180 mg, from the lis302dl application note) seems
+empirically good to keep the accelerometers quiet while riding a (calm)
+train.
+
+
+The patch moves the sample reading for the accelerometers from
+mach-gta02.c to lis302dl.c and instead exports the generic
+lis302dl_bitbang function. This is to easier support both "raw" data
+reading and reading with a threshold in the future (not yet implemented).
