Description:

		Mounting matrix for IIO sensors. This is a rotation matrix which

		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.
