+* 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, and any other clocks to be
+          switched by runtime_pm
+- clock-names: Required only if more than a single clock is listed in 'clocks'.
+               The PHY reference clock must be named 'phy_refclk'
+- phy-mode: See ethernet.txt file in the same directory
+- phy-handle: phandle to select child 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
+- mac-address
+- max-speed
+- max-frame-size
+
+Required properties for the child phy:
+- reg: phy address
+
+Example:
+       eth0: netsec@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>;
+               phy-mode = "rgmii";
+               max-speed = <1000>;
+               max-frame-size = <9000>;
+               phy-handle = <&ethphy0>;
+
+               #address-cells = <1>;
+               #size-cells = <0>;
+
+               ethphy0: ethernet-phy@1 {
+                       compatible = "ethernet-phy-ieee802.3-c22";
+                       reg = <1>;
+               };
+       };
