Hello Neil, Thank you for reviewing it. I have sent out v3 with the following changes: * Fixed speed-map indentation, * Aligned bracket * Sorted cpu_thermal node in alphabetical order. * Changed cooling-device * Increased temperature to 70°C I hope that is fine.

GS-King-X has a single speed GPIO fan which is always-on by default. If we add controls for the fan and a trip point, the fan stays off most of the time, reducing background noise from the unit.
