Add the core driver for the BNO055 IMU from Bosch. This IMU can be connected via both serial and I2C busses; separate patches will add support for them. The driver supports "AMG" (Accelerometer, Magnetometer, Gyroscope) mode, that provides raw data from the said internal sensors, and a couple of "fusion" modes (i.e. the IMU also does calculations in order to provide euler angles, quaternions, linear acceleration and gravity measurements). In fusion modes the AMG data is still available (with some calibration refinements done by the IMU), but certain settings such as low pass filters cut-off frequency and sensors' ranges are fixed, while in AMG mode they can be customized; this is why AMG mode can still be interesting.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
