1* Marvell Armada 375 Ethernet Controller (PPv2.1)
2  Marvell Armada 7K/8K Ethernet Controller (PPv2.2)
3
4Required properties:
5
6- compatible: should be one of:
7    "marvell,armada-375-pp2"
8    "marvell,armada-7k-pp2"
9- reg: addresses and length of the register sets for the device.
10  For "marvell,armada-375-pp2", must contain the following register
11  sets:
12	- common controller registers
13	- LMS registers
14	- one register area per Ethernet port
15  For "marvell,armada-7k-pp2", must contain the following register
16  sets:
17	- packet processor registers
18	- networking interfaces registers
19
20- clocks: pointers to the reference clocks for this device, consequently:
21	- main controller clock (for both armada-375-pp2 and armada-7k-pp2)
22	- GOP clock (for both armada-375-pp2 and armada-7k-pp2)
23	- MG clock (only for armada-7k-pp2)
24	- MG Core clock (only for armada-7k-pp2)
25	- AXI clock (only for armada-7k-pp2)
26- clock-names: names of used clocks, must be "pp_clk", "gop_clk", "mg_clk",
27  "mg_core_clk" and "axi_clk" (the 3 latter only for armada-7k-pp2).
28
29The ethernet ports are represented by subnodes. At least one port is
30required.
31
32Required properties (port):
33
34- interrupts: interrupt for the port
35- port-id: ID of the port from the MAC point of view
36- gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the
37  GOP (Group Of Ports) point of view. This ID is used to index the
38  per-port registers in the second register area.
39- phy-mode: See ethernet.txt file in the same directory
40
41Optional properties (port):
42
43- marvell,loopback: port is loopback mode
44- phy: a phandle to a phy node defining the PHY address (as the reg
45  property, a single integer).
46- interrupt-names: if more than a single interrupt for rx is given, must
47                   be the name associated to the interrupts listed. Valid
48                   names are: "tx-cpu0", "tx-cpu1", "tx-cpu2", "tx-cpu3",
49		   "rx-shared", "link".
50- marvell,system-controller: a phandle to the system controller.
