+ informs userspace about sensor chip's placement relative to the
+ main hardware it is mounted on.
+ Main hardware placement is defined according to the local
+ reference frame related to the physical quantity the sensor
+ measures.
+ Given that the rotation matrix is defined in a board specific
+ way (platform data and / or device-tree), the main hardware
+ reference frame definition is left to the implementor's choice
+ (see below for a magnetometer example).
+ Applications should apply this rotation matrix to samples so
+ that when main hardware reference frame is aligned onto local
+ reference frame, then sensor chip reference frame is also
+ perfectly aligned with it.
+ Matrix is a 3x3 unitary matrix and typically looks like
+ [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix
+ [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware
+ are perfectly aligned with each other.
+
+ For example, a mounting matrix for a magnetometer sensor informs
+ userspace about sensor chip's ORIENTATION relative to the main
+ hardware.
+ More specifically, main hardware orientation is defined with
+ respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where :
+ * Y is in the ground plane and positive towards magnetic North ;
+ * X is in the ground plane, perpendicular to the North axis and
+ positive towards the East ;
+ * Z is perpendicular to the ground plane and positive upwards.
+
+ An implementor might consider that for a hand-held device, a
+ 'natural' orientation would be 'front facing camera at the top'.
+ The main hardware reference frame could then be described as :
+ * Y is in the plane of the screen and is positive towards the
+ top of the screen ;
+ * X is in the plane of the screen, perpendicular to Y axis, and
+ positive towards the right hand side of the screen ;
+ * Z is perpendicular to the screen plane and positive out of the
+ screen.
+ Another example for a quadrotor UAV might be :
+ * Y is in the plane of the propellers and positive towards the
+ front-view camera;
+ * X is in the plane of the propellers, perpendicular to Y axis,
+ and positive towards the starboard side of the UAV ;
+ * Z is perpendicular to propellers plane and positive upwards.
