1 * Marvell Armada 375 Ethernet Controller (PPv2.1)
2   Marvell Armada 7K/8K Ethernet Controller (PPv2.2)
3   Marvell CN913X Ethernet Controller (PPv2.3)
4
5 Required properties:
6
7 - compatible: should be one of:
8     "marvell,armada-375-pp2"
9     "marvell,armada-7k-pp2"
10 - reg: addresses and length of the register sets for the device.
11   For "marvell,armada-375-pp2", must contain the following register
12   sets:
13         - common controller registers
14         - LMS registers
15         - one register area per Ethernet port
16   For "marvell,armada-7k-pp2" used by 7K/8K and CN913X, must contain the following register
17   sets:
18         - packet processor registers
19         - networking interfaces registers
20         - CM3 address space used for TX Flow Control
21
22 - clocks: pointers to the reference clocks for this device, consequently:
23         - main controller clock (for both armada-375-pp2 and armada-7k-pp2)
24         - GOP clock (for both armada-375-pp2 and armada-7k-pp2)
25         - MG clock (only for armada-7k-pp2)
26         - MG Core clock (only for armada-7k-pp2)
27         - AXI clock (only for armada-7k-pp2)
28 - clock-names: names of used clocks, must be "pp_clk", "gop_clk", "mg_clk",
29   "mg_core_clk" and "axi_clk" (the 3 latter only for armada-7k-pp2).
30
31 The ethernet ports are represented by subnodes. At least one port is
32 required.
33
34 Required properties (port):
35
36 - interrupts: interrupt(s) for the port
37 - port-id: ID of the port from the MAC point of view
38 - gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the
39   GOP (Group Of Ports) point of view. This ID is used to index the
40   per-port registers in the second register area.
41 - phy-mode: See ethernet.txt file in the same directory
42
43 Optional properties (port):
44
45 - marvell,loopback: port is loopback mode
46 - phy: a phandle to a phy node defining the PHY address (as the reg
47   property, a single integer).
48 - interrupt-names: if more than a single interrupt for is given, must be the
49                    name associated to the interrupts listed. Valid names are:
50                    "hifX", with X in [0..8], and "link". The names "tx-cpu0",
51                    "tx-cpu1", "tx-cpu2", "tx-cpu3" and "rx-shared" are supported
52                    for backward compatibility but shouldn't be used for new
53                    additions.
54 - marvell,system-controller: a phandle to the system controller.
