H A Dthermal.txt1 * Thermal Framework Device Tree descriptor
4 defining hardware thermal structure using device tree.
5 A thermal structure includes thermal zones and their components,
9 The target of device tree thermal descriptors is to describe only
10 the hardware thermal aspects. The thermal device tree bindings are
14 There are five types of nodes involved to describe thermal bindings:
15 - thermal sensors: devices which may be used to take temperature
17 - cooling devices: devices which may be used to dissipate heat.
18 - trip points: describe key temperatures at which cooling is recommended. The
20 - cooling maps: used to describe links between trip points and cooling devices;
