From 22087c850e8e56c5959640260ab3fa974556ef96 Mon Sep 17 00:00:00 2001 From: Gwendal Grignou Date: Mon, 26 Aug 2019 16:02:58 -0700 Subject: iio: cros_ec: set calibscale for 3d MEMS to unit vector By default, set the calibscale vector to unit vector. When calibrating one axis, the other axis calibrations are sent as well. If left to 0, sensor data from uncalibrated axis are zero'ed out until all axis are calibrated.
