Michal Wilczynski has verified that this driver will work on StarFive
JH7110 with some extra glue drivers (but without modification to this
driver itself). [1]

Although this can be considered as future work and changing to
ARCH_THEAD seems okay now.

(BTW the hardware identification values is taken from the vendor driver
and it should support different variants of DC8200)

Thanks
