* Socionext NetSec Ethernet Controller IP

Required properties:
- compatible: Should be "socionext,synquacer-netsec"
- reg: Address and length of the control register area, followed by the
       address and length of the EEPROM holding the MAC address and
       microengine firmware
- interrupts: Should contain ethernet controller interrupt
- clocks: phandle to the PHY reference clock
- clock-names: Should be "phy_ref_clk"
- phy-mode: See ethernet.txt file in the same directory
- phy-handle: See ethernet.txt in the same directory.

- mdio device tree subnode: When the Netsec has a phy connected to its local
		mdio, there must be device tree subnode with the following
		required properties:

	- #address-cells: Must be <1>.
	- #size-cells: Must be <0>.

	For each phy on the mdio bus, there must be a node with the following
	fields:
	- compatible: Refer to phy.txt
	- reg: phy id used to communicate to phy.

Optional properties: (See ethernet.txt file in the same directory)
- dma-coherent: Boolean property, must only be present if memory
	accesses performed by the device are cache coherent.
- local-mac-address: See ethernet.txt in the same directory.
- mac-address: See ethernet.txt in the same directory.
- max-speed: See ethernet.txt in the same directory.
- max-frame-size: See ethernet.txt in the same directory.

Example:
	eth0: ethernet@522d0000 {
		compatible = "socionext,synquacer-netsec";
		reg = <0 0x522d0000 0x0 0x10000>, <0 0x10000000 0x0 0x10000>;
		interrupts = <GIC_SPI 176 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&clk_netsec>;
		clock-names = "phy_ref_clk";
		phy-mode = "rgmii";
		max-speed = <1000>;
		max-frame-size = <9000>;
		phy-handle = <&phy1>;

		mdio {
			#address-cells = <1>;
			#size-cells = <0>;
			phy1: ethernet-phy@1 {
				compatible = "ethernet-phy-ieee802.3-c22";
				reg = <1>;
			};
		};
