1 * Marvell Armada 375 Ethernet Controller (PPv2.1)
2   Marvell Armada 7K/8K Ethernet Controller (PPv2.2)
3
4 Required 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 - clock-names: names of used clocks, must be "pp_clk", "gop_clk" and
25   "mg_clk" (the latter only for armada-7k-pp2).
26
27 The ethernet ports are represented by subnodes. At least one port is
28 required.
29
30 Required properties (port):
31
32 - interrupts: interrupt for the port
33 - port-id: ID of the port from the MAC point of view
34 - gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the
35   GOP (Group Of Ports) point of view. This ID is used to index the
36   per-port registers in the second register area.
37 - phy-mode: See ethernet.txt file in the same directory
38
39 Optional properties (port):
40
41 - marvell,loopback: port is loopback mode
42 - phy: a phandle to a phy node defining the PHY address (as the reg
43   property, a single integer).
44 - interrupt-names: if more than a single interrupt for rx is given, must
45                    be the name associated to the interrupts listed. Valid
46                    names are: "tx-cpu0", "tx-cpu1", "tx-cpu2", "tx-cpu3",
47                    "rx-shared", "link".
48 - marvell,system-controller: a phandle to the system controller.
