+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).
