I have a Colorfly e708q1 tablet. This was supported by Sunxi. I have successfully managed to run Arch on it with an 5.x kernel (display does work and wifi also), but the AXP20x power chip, energy management is not working. I have, for example no battery device. (The official guide's kernel compiling is not working, i have no display with it, or it's not booting.)

Can someone please help how to get the AXP20x working (udev rules missing? etc...) Seems a kernel module is present, but energy management is completely missing.

I can provide information if needed, but i completely don't know how to get the AXP20x working.

(Want to use the tablet as a wireless display, and without power management, it's too hot.)
