The short discuss you can find on https://lkml.org/lkml/2018/11/30/502. Quotation: " >> Frankly, I don't understand why this is a series.

Pawel, you could remove the "RFC" prefix, and send the whole >one as one patch. I will test it at my hardware. 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 Pawel Laszczak.
