[PATCH v2 1/1] arm64: dts: meson: add gpio-fan control to GS-King-X

[Furkan Kardame]

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.
