+* 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@...d0000 {
+ 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>;
+ };
+ };
