This commit adds a new network driver for the network controller in Marvell Armada 375 SoC. Given the controller is very different from the ones in the other Marvell SoCs that use the mv643xx_eth (Kirkwood, Orion, Discovery) and mvneta (Armada 370/38x/XP) drivers, a new driver is needed.

* Marvell Armada 375 Ethernet Controller (PPv2)
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "marvell,armada-375-pp2"
|
|
- reg: addresses and length of the register sets for the device.
|
|
Must contain the following register sets:
|
|
- common controller registers
|
|
- LMS registers
|
|
In addition, at least one port register set is required.
|
|
- clocks: a pointer to the reference clocks for this device, consequently:
|
|
- main controller clock
|
|
- GOP clock
|
|
- clock-names: names of used clocks, must be "pp_clk" and "gop_clk".
|
|
|
|
The ethernet ports are represented by subnodes. At least one port is
|
|
required.
|
|
|
|
Required properties (port):
|
|
|
|
- interrupts: interrupt for the port
|
|
- port-id: should be '0' or '1' for ethernet ports, and '2' for the
|
|
loopback port
|
|
- 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). Note: if this property isn't present,
|
|
then fixed link is assumed, and the 'fixed-link' property is
|
|
mandatory.
|
|
|
|
Example:
|
|
|
|
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";
|
|
};
|
|
};
