Subject: [net-next 0/4] net: ethernet: renesas: rcar_gen4_ptp: Hide private data

Hello,

The R-Car Gen4 PTP module started out as an exclusive feature of a 
single driver, but have since been extended to cover both R-Car Switch 
and TSN driver implementations on Gen4.

The feature have already been extended to be built as its own module 
with an interface exposed thru a local header file. The header file 
however also exposes the modules private data structure. The two 
existing users have already started to poke at members of the struct.  

The exposed private data being manipulated by users makes refactoring 
and future rework hard as the interface for the module becomes to 
chaotic. This small series aims to create two helpers to hide the 
private data.

This is done as a small preparation before a third, new, users of the 
Gen4 PTP will be added in a follow up series.
