Is innosilicon the same thing as verisilicon? Also
s/transmiter/transmitter/, both here and in the title.

Is this going to work on every SoC that StarFive has ever & will ever
make? Please use soc-based compatibles ;)

You only have one item here, you don't need the "items: - const:",
"const:" alone will do.

Is it based on Verisilicon IP, or is it exactly that verisilicon IP? I

...the compatible is the verisilicon IP. I would be a lot happier if
the compatibles were set yp for something like:
"starfive,jh7110-foo", "verisilicon,dc8200"

This should be in it's own patch.
