* Marvell Armada 375 Ethernet Controller (PPv2.1)
  Marvell Armada 7K/8K Ethernet Controller (PPv2.2)

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", must contain the following register
  sets:
	- packet processor registers
	- networking interfaces registers

- 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 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 rx is given, must
                   be the name associated to the interrupts listed. Valid
                   names are: "tx-cpu0", "tx-cpu1", "tx-cpu2", "tx-cpu3",
		   "rx-shared", "link".
- marvell,system-controller: a phandle to the system controller.
