Description
Hi,
I plugged in a 24v fan on the SoC fan socket (internal pin PC15) of the Manta M4P. The fan is not working because apparently an overlay is needed that makes the H616 SoC communicate with the fan's GPIO to turn it on/off depending on the SoC's temperature.
An example of this kind of overlay for Raspberry Pi can be found here: https://raw.githubusercontent.com/raspberrypi/linux/rpi-4.19.y/arch/arm/boot/dts/overlays/gpio-fan-overlay.dts .
It would be nice to have something like this adjusted for CB1.

Research direction
Start with the Raspberry Pi gpio-fan-overlay.dts example linked in the issue and inspect the CB1 H616 device-tree sources for the Manta M4P and GPIO PC15. Confirm the expected temperature-controlled fan behavior and existing overlay conventions; done means the SoC fan can be switched on and off according to temperature on CB1.
