All these controls needs admin privilege to update.



``enable`` (RW)

	1 for enable, 0 for disable. Shows the current enable status of

	platform temperature control feature. User space can enable/disable

	hardware controls.



``temperature_target`` (RW)

	Update a new temperature target in milli degree celsius for hardware to

	use for the temperature control.



Given that this is platform temperature control, it is expected that a

single user-level manager owns and manages the controls. If multiple

user-level software applications attempt to write different targets, it

can lead to unexpected behavior.
