+Description:
+		Some OneXPlayer devices (e.g., X1 series) feature a little LED
+		nested in the Turbo button. This LED is illuminated when the
+		device is in the higher TDP mode (e.g., 25W). Once tt_toggle
+		is engaged, this LED is left dangling to its last state. This
+		attribute allows userspace to control the LED state manually
+		(either with 1 or 0). Only a subset of devices contain this LED.
