I added support for cpufreq and temperature sensors. Now you can enjoy (almost) full power of your new allwinner with mainline kernel.
To do this, update the linux-a523 package with the command sudo pacman -U path-to/linux-h728-6.14-2-aarch64.pkg.tar.zst
Do not use this package with processors other than H728/A523/A527/T527
Since this is the first attempt at implementing these drivers, the performance governor is chosen for more stability. You can switch to ondemand if you wish.
Also patches for sdio wifi support are taken from warpme’s repos. So the built-in wifi of the AIC8800 is now working. You need to install the package aic8800d80-firmware-2025.03-1-any.pkg.tar.zst
Still not working:
ethernet, USB3/PCIe, display engine stuff, gpu, audio, etc

Here 7z b comparison with opi-zero3 (more than x2 performance) h618_vs_h728 · GitHub
UPD: I have identified one problem with the new kernel, it only works after rebooting from android. I think I know what the problem might be and will try to fix it next weekend
