While sun8i might make some sense technically, all 64-bit sunxi
compatible strings use the sun50i prefix to follow the Allwinner naming.
So this should read:
"allwinner,sun50i-a64-system-controller"
Also I am wondering if we should add a compatible string for the H5
(support for that SoC is in -next already):
"allwinner,sun50i-h5-system-controller"
Cheers,
Andre.
