5Description:
6		Takeover TDP controls from the device. OneXPlayer devices have a
7		turbo button that can be used to switch between two TDP modes
8		(usually 15W and 25W). By setting this attribute to 1, this
9		functionality is disabled, handing TDP control over to (Windows)
10		userspace software and the Turbo button turns into a keyboard
11		shortcut over the AT keyboard of the device. In addition,
12		using this setting is a prerequisite for PWM control for most
13		newer models (otherwise it NOOPs).
