* Marvell Armada 375 Ethernet Controller (PPv2.1)
|
|
Marvell Armada 7K/8K Ethernet Controller (PPv2.2)
|
|
Marvell CN913X Ethernet Controller (PPv2.3)
|
|
|
|
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" used by 7K/8K and CN913X, must contain the following register
|
|
sets:
|
|
- packet processor registers
|
|
- networking interfaces registers
|
|
- CM3 address space used for TX Flow Control
|
|
|
|
- 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(s) 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 is given, must be the
|
|
name associated to the interrupts listed. Valid names are:
|
|
"hifX", with X in [0..8], and "link". The names "tx-cpu0",
|
|
"tx-cpu1", "tx-cpu2", "tx-cpu3" and "rx-shared" are supported
|
|
for backward compatibility but shouldn't be used for new
|
|
additions.
|
|
- marvell,system-controller: a phandle to the system controller.
|
|
|
|
