Hello all, This is a patch series to add support to slope and offset constants of a linear extrapolation model. This type of model is very common across different platforms, and many drivers are attempting to have its support.
The basic idea is to have this mapping in the thermal core, as part of thermal_zone_params. In this series, I also add a simple support to read them from DT, i.e.: /* hotspot = 1 * adc + 6000 */ coefficients = <1 6000>; I am copying some of the driver writers that attempted to use this feature, but by adding their own property. Please, check if this change is enough to properly map your slope and offset requirement. Remember, they will be added in your thermal zone DT node, instead of in your sensor DT node.
