From f9992af62fbf3a50d89d1f3914b2ff5cda187466 Mon Sep 17 00:00:00 2001 From: Jonathan Bakker Date: Thu, 14 May 2020 13:48:55 -0700 Subject: [PATCH] iio: accel: bma180: Prepare for different reset values Some variants of the bma180 (eg bma023) have different reset values. In preparation for adding support for them, factor out the reset value into the chip specific data.
