In the past driver was split into series of patch, but it was difficult to review for other
reviewers so I made decision to prepare it in this way.
The short discuss you can find on https://lkml.org/lkml/2018/11/30/502.

Ok, I will prepare such single patch.
Peter I know that you have little different platform.
Probably you should made some additional changes for your platform.

Thanks
