The PPE (packet processing engine) is the network processing hardware 
block in QCOM IPQ SoC. It includes the ethernet MAC and UNIPHY(PCS). 
This driver is the base PPE driver which brings up the PPE and handles 
MAC/UNIPHY operations. QCA8084 is the external 2.5Gbps 4-port PHY 
device, which can be connected with PPE integrated MAC by UNIPHY(PCS).

Here is the relationship.
PPE integrated MAC --- PPE integrated UNIPHY(PCS) --- (PCS)QCA8084.

Yes, Jakub, there are two authors in these patch series, Lei Wei and me.
The patches are already ready for some time, the code has been verified
on the Qualcomm reference design board. These are not downstream drivers
but drivers re-written for upstream.

Sorry for trouble caused, will learn about the guidance provided by
the review comments, and follow up on the guidance and have the full
internal review of the patch updates before pushing the patch series.
