-Required properties for dp-controller:

-               platform specific such as:

-       -interrupts:
-               interrupt combiner values.
-       -clocks:
-               from common clock binding: handle to dp clock.
-       -clock-names:
-               from common clock binding: Shall be "dp".
-       -phys:
-               from general PHY binding: the phandle for the PHY device.
-       -phy-names:
-               from general PHY binding: Should be "dp".

-               Indicates which GPIO should be used for hotplug detection
-       -port@[X]: SoC specific port nodes with endpoint definitions as defined
