Sorry for the late feedback, since this is a new driver, things outline
below can still be submitted as incremental fixes.

We typically use "-" to separate words in DT properties, not "_". I am
not sure about the required nature of these 3 proprietary/specific
properties, cannot there be good reset defaults from the HW in any case?
You might want to add a reference to net/phy.txt for the remaiming DT
properties.

This one has not been converted to use the phy_interface_is_rgmii()
helper, but in fact, once you do that, you could probably just add an
early check for this condition, return, and reduce the indentation for
the normal case/RGMII, and eliminate two redundant condition checks.
Thanks!
