So you still have not look at the work Christian is doing. You must
work together with Christian. This driver is not going to be accepted
unless you do.

Which of these properties exist for the Pure PHY device? Which exist
for the integrated switch? And by that, i mean which are actual pins
on the PHY device? We need the device tree binding to list which
properties are required for each use case.
