10 Mounting matrix
12 The mounting matrix is a device tree property used to orient any device
16 The purpose of the mounting matrix is to translate the sensor frame of
17 reference into the device frame of reference using a translation matrix as
43 to this world. When using the mounting matrix, the sensor and device orientation
154 To achieve this, use the device tree property "mount-matrix" for the sensor.
156 This supplies a 3x3 rotation matrix in the strict linear algebraic sense,
159 multiplied by this matrix to give the proper vectors values in three-dimensional
165 The mounting matrix has the layout:
