Dsysfs-api.rst15 The generic thermal sysfs provides a set of interfaces for thermal zone
16 devices (sensors) and thermal cooling devices (fan, processor...) to register
17 with the thermal management solution and to be a part of it.
19 This how-to focuses on enabling new thermal zone and cooling devices to
20 participate in thermal management.
21 This solution is platform independent and any type of thermal zone devices
24 The main task of the thermal sysfs driver is to expose thermal zone attributes
