Thermal estimator driver.
|
||
|
|
|
||
|
|
Properties :
|
||
|
|
- compatible : Should contain "nvidia,therm-est".
|
||
|
|
- polling-period : Polling wait times for thermal estimation, in milliseconds.
|
||
|
|
- tc1 : Coefficient 1 for thermal trend calculation.
|
||
|
|
- tc2 : Coefficient 2 for thermal trend calculation.
|
||
|
|
- node for subdev : Node for subdevice information. Required.
|
||
|
|
|
||
|
|
Properties in subdev node : Required.
|
||
|
|
- subdev_names : list of strings. It contains list of the name of the therm
|
||
|
|
zones used for estimation.
|
||
|
|
- node for coeff_set : contains a set of zone specific coefficients+offset.
|
||
|
|
This node can be numerous.
|
||
|
|
|
||
|
|
Properties in coeff_set : Required. Can be numerous.
|
||
|
|
- toffset : Temperature offset for thermal estimation, in milli-celsius.
|
||
|
|
- coeffs : An array of coefficients, the number of entries should be twenty
|
||
|
|
per sub device.
|
