From a1a5cfe70cd29a59a9a85290dfe95ed1c8df1193 Mon Sep 17 00:00:00 2001 From: Cosmin Tanislav Date: Mon, 14 Feb 2022 09:38:06 +0200 Subject: [PATCH] iio: introduce mag_referenced Some accelerometers that support activity and inactivity events also support a referenced mode, in which the gravitational acceleration is taken as a point of reference before comparing the acceleration to the specified activity and inactivity magnitude. For example, in the case of the ADXL367, for activity detection, the formula is: abs(acceleration - reference) > magnitude Add a new event type that makes this behavior clear.
