Subject: [PATCH net-next v3 2/6] dt-bindings: marvell: Add Marvell
 MV88E6060 DSA schema

The Marvell MV88E6060 is one of the oldest DSA switches from
Marvell, and it has DT bindings used in the wild. Let's define
them properly.

It is different enough from the rest of the MV88E6xxx switches
that it deserves its own binding.

+description:
+  The Marvell MV88E6060 switch has been produced and sold by Marvell
+  since at least 2010. The switch has one pin ADDR4 that controls the
+  MDIO address of the switch to be 0x10 or 0x00, and on the MDIO bus
+  connected to the switch, the PHY:s inside the switch appear as
+  independent devices on address 0x00-0x04 or 0x10-0x14, so in difference
+  from many other DSA switches this switch does not have an internal
+  MDIO bus for the PHY devices.

+    description:
+      The MV88E6060 is the oldest Marvell DSA switch product, and
+      as such a bit limited in features compared to later hardware.
