      iio:core: mounting matrix support · dfc57732
      Gregor Boirie authored
      Expose a rotation matrix to indicate userspace the chip placement with
      respect to the overall hardware system. This is needed to adjust
      coordinates sampled from a sensor chip when its position deviates from the
      main hardware system.
      
      Final coordinates computation is delegated to userspace since:
      * computation may involve floating point arithmetics ;
      * it allows an application to combine adjustments with arbitrary
        transformations.
      
      This 3 dimentional space rotation matrix is expressed as 3x3 array of
      strings to support floating point numbers. It may be retrieved from a
      "[<dir>_][<type>_]mount_matrix" sysfs attribute file. It is declared into a
      device / driver specific DTS property or platform data.
