+* Marvell Armada 375 Ethernet Controller (PPv2.1)
+  Marvell Armada 7K/8K Ethernet Controller (PPv2.2)
+  Marvell CN913X Ethernet Controller (PPv2.3)
+
+Required properties:
+
+- compatible: should be one of:
+    "marvell,armada-375-pp2"
+    "marvell,armada-7k-pp2"
+- reg: addresses and length of the register sets for the device.
+  For "marvell,armada-375-pp2", must contain the following register
+  sets:
+	- common controller registers
+	- LMS registers
+	- one register area per Ethernet port
+  For "marvell,armada-7k-pp2" used by 7K/8K and CN913X, must contain the following register
+  sets:
+	- packet processor registers
+	- networking interfaces registers
+	- CM3 address space used for TX Flow Control
+
+- clocks: pointers to the reference clocks for this device, consequently:
+	- main controller clock (for both armada-375-pp2 and armada-7k-pp2)
+	- GOP clock (for both armada-375-pp2 and armada-7k-pp2)
+	- MG clock (only for armada-7k-pp2)
+	- MG Core clock (only for armada-7k-pp2)
+	- AXI clock (only for armada-7k-pp2)
+- clock-names: names of used clocks, must be "pp_clk", "gop_clk", "mg_clk",
+  "mg_core_clk" and "axi_clk" (the 3 latter only for armada-7k-pp2).
+
+The ethernet ports are represented by subnodes. At least one port is
+required.
+
+Required properties (port):
+
+- interrupts: interrupt(s) for the port
+- port-id: ID of the port from the MAC point of view
+- gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the
+  GOP (Group Of Ports) point of view. This ID is used to index the
+  per-port registers in the second register area.
+- phy-mode: See ethernet.txt file in the same directory
+
+Optional properties (port):
+
+- marvell,loopback: port is loopback mode
+- phy: a phandle to a phy node defining the PHY address (as the reg
+  property, a single integer).
+- interrupt-names: if more than a single interrupt for is given, must be the
+                   name associated to the interrupts listed. Valid names are:
+                   "hifX", with X in [0..8], and "link". The names "tx-cpu0",
+                   "tx-cpu1", "tx-cpu2", "tx-cpu3" and "rx-shared" are supported
+                   for backward compatibility but shouldn't be used for new
+                   additions.
+- marvell,system-controller: a phandle to the system controller.
