Subject: [PATCH] iio: imu: Add mpu9255 support to mpu6050 driver
Date: Mon, 2 Apr 2018 18:42:00 -0400	[thread overview]
Message-ID: <20180402184200.0aa65204@Constantine> (raw)

Added support for the mpu9255 IMU to the mpu6050 driver. The
register map is the same as the other chips; the only driver
difference is the compatible string and the WHOAMI register
value.
