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 ask because...

...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"

Same here.

This should be in it's own patch.
Cheers, Conor.
