* 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)
- clock-names: names of used clocks, must be "pp_clk", "gop_clk" and
"mg_clk" (the 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).
