+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.
