=============================================

TEST COMPILED ONLY!
Driver not verified with hardware!
Produced in the hope that we can get some review progress
with this serie for the documents and driver.
Use at your own risk!

Renamed the combi phy driver to multi phy to highlight the different approach and
not to confuse with the driver from the Rockchip manufacturer tree.
By using a parent node it makes it hopefully easier to coordinate
for new futures/functions between nodes.

Removed a few properties, because it's not entire clear how they should be used.
To prevent the obligation to keep supporting them despite changed handling.
