* 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).
Example for marvell,armada-375-pp2:
ethernet@f0000 {
compatible = "marvell,armada-375-pp2";
reg = <0xf0000 0xa000>,
<0xc0000 0x3060>,
<0xc4000 0x100>,
<0xc5000 0x100>;
clocks = <&gateclk 3>, <&gateclk 19>;
clock-names = "pp_clk", "gop_clk";
status = "okay";
eth0: eth0@c4000 {
interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>;
port-id = <0>;
status = "okay";
phy = <&phy0>;
phy-mode = "gmii";
};
eth1: eth1@c5000 {
interrupts = <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>;
port-id = <1>;
status = "okay";
phy = <&phy3>;
phy-mode = "gmii";
};
};
Example for marvell,armada-7k-pp2:
cpm_ethernet: ethernet@0 {
compatible = "marvell,armada-7k-pp22";
reg = <0x0 0x100000>, <0x129000 0xb000>;
clocks = <&cpm_syscon0 1 3>, <&cpm_syscon0 1 9>, <&cpm_syscon0 1 5>;
clock-names = "pp_clk", "gop_clk", "gp_clk";
eth0: eth0 {
interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>;
port-id = <0>;
gop-port-id = <0>;
};
eth1: eth1 {
interrupts = <GIC_SPI 38 IRQ_TYPE_LEVEL_HIGH>;
port-id = <1>;
gop-port-id = <2>;
};
eth2: eth2 {
interrupts = <GIC_SPI 39 IRQ_TYPE_LEVEL_HIGH>;
port-id = <2>;
gop-port-id = <3>;
};
};
