    thermal: support slope and offset coefficients · 9d0be7f4
    Eduardo Valentin authored
    It is common to have a linear extrapolation from
    the current sensor readings and the actual temperature
    value. This is specially the case when the sensor
    is in use to extrapolate hotspots.
    
    This patch adds slope and offset constants for
    single sensor linear extrapolation equation. Because
    the same sensor can be use in different locations,
    from board to board, these constants are added
    as part of thermal_zone_params.
    
    The constants are available through sysfs.
    
    It is up to the device driver to determine
    the usage of these values.
