ethernet: Add new driver for Marvell Armada 375 network unit 



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";

	};

};
