From fbced0e9465152d628ece5fd0d11de4e7a1f5ce5 Mon Sep 17 00:00:00 2001 From: Crestez Dan Leonard Date: Wed, 20 Apr 2016 16:15:13 +0300 Subject: iio: inv_mpu6050: Add explicit support for MPU9150 This device is a package containing a MPU6050-like sensor and an AK8975 magnetometer. The magnetometer component is supported by the existing ak8975 driver. This patch also rephrases the Kconfig descriptions.
