I think my main comment and question for this driver is; what 
specifically about the sm8550 requires an entirely new driver for the 
venus block ?

We have a re-implementation of the HFI as an example.

What are the specifics of the technical barriers, if any, that preclude 
adding or extending the existing venus codebase to enable the new silicon ?
