This cache controller is also used on the StarFive JH7110 SoC.

"... and configured identically to that of the FU740"?
Anyways,

Actually, after looking at the next patch - why can you not fall back to
the fu740 one since you appear to have the same configuration as it?

Right, I will drop this patch and use "sifive,fu740-c000-ccache" as
compatible in dts.

Uh, that's not quite what I was suggesting. Rather than using that one
in isolation, you can do the following in your dt:
"starfive,jh7110-ccache", "sifive,fu740-c000-ccache"

And then in the driver we need to make no changes - unless down the line
we find some sort of issue that requires special handling etc. There's
no harm in having a "starfive,jh7110-ccache" IMO.

Yeah, sifive,ccache0 is probably the generic one which would get
this working.
