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