Could you please settle on a single prefix for all your function names?
Ideally it should be close to the driver name. It's hard to understand
that the function comes from the verisilicon driver if its name starts
from dc_ or especially with plane_.
I'd strongly suggest to stop defining anything outside of the selected
vs_ namespace.

These types are largely unused within this patch. Please drop all the
unused parts and add them later, when required.
