14 Thermal management is achieved in devicetree
15 and the software abstraction of thermal zone
16 action to mitigate thermal overloads.
17
18 The following node types are used to complet
19 system in devicetree:
20 - thermal-sensor: device that measures temp
21 - cooling-device: device used to dissipate
22 - thermal-zones: a container of the followi
23 thermal data for the platform

25 This binding describes the thermal-sensor.

27 Thermal sensor devices provide temperature s
28 zones. Typical devices are I2C ADC converter
29 devices may control one or more internal sen
