-* 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.
-- max-speed: See ethernet.txt in the same directory.
-- max-frame-size: See ethernet.txt in the same directory.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt. The 'phy-mode' property is required, but may
-be set to the empty string if the PHY configuration is programmed by
-the firmware or set by hardware straps, and needs to be preserved.
-
-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>;
-			};
-		};
