From bcc57a48eaee63a71983996c4c9d89ce7cbf55d9 Mon Sep 17 00:00:00 2001 From: Andrea Merello Date: Wed, 7 Sep 2022 15:21:52 +0200 Subject: iio: add modifiers for linear acceleration Add IIO_MOD_LINEAR_X, IIO_MOD_LINEAR_Y and IIO_MOD_LINEAR_Z modifiers to te IIO core, which is preparatory for adding the Bosch BNO055 IMU driver. Bosch BNO055 IMU can report raw accelerations (among x, y and z axis) as well as the so called "linear accelerations" (again, among x, y and z axis) which is basically the acceleration after subtracting gravity and for which those new modifiers are for.
