Contrary to the IMU at the head, a bit needs to be set to
make probe of the magnetometer successful.

Changes in V3:
- correct another - vs _ issue in device tree
- more standard kernel version description

Changes in V2:
- add types in binding doc
- more description / comments in binding doc
- limit register change to imu9150
- correct node name in device tree (- vs _)

Andreas Kemnade (3):
  dt-bindings: iio: imu: mpu6050: Add level shifter
  iio: imu: mpu6050: add level shifter flag
  ARM: dts: omap: omap4-embt2ws: Add IMU at control unit
