It's an automatic mechanism that cannot be actively controlled. Do not expose it as a cooling device and instead of tying it to a specific trip point, hard-code the temperature at which the automatic throttling will begin. While at it, clean up the trip point names to reflect the names used by the thermal device tree bindings.
