+* Freescale Fast Ethernet Controller (FEC)
+
+Required properties:
+- compatible : Should be "fsl,<soc>-fec"
+- reg : Address and length of the register set for the device
+- interrupts : Should contain fec interrupt
+- phy-mode : See ethernet.txt file in the same directory
+
+Optional properties:
+- phy-supply : regulator that powers the Ethernet PHY.
+- phy-handle : phandle to the PHY device connected to this device.
+- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
+  Use instead of phy-handle.
+- fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
+  hw multi queues. Should specify the tx queue number, otherwise set tx queue
+  number to 1.
+- fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
+  hw multi queues. Should specify the rx queue number, otherwise set rx queue
+  number to 1.
+- fsl,magic-packet : If present, indicates that the hardware supports waking
+  up via magic packet.
+- fsl,err006687-workaround-present: If present indicates that the system has
+  the hardware workaround for ERR006687 applied and does not need a software
+  workaround.
+- fsl,stop-mode: register bits of stop mode control, the format is
+		 <&gpr req_gpr req_bit>.
+		 gpr is the phandle to general purpose register node.
+		 req_gpr is the gpr register offset for ENET stop request.
+		 req_bit is the gpr bit offset for ENET stop request.
+ -interrupt-names:  names of the interrupts listed in interrupts property in
+  the same order. The defaults if not specified are
+  __Number of interrupts__   __Default__
+	1			"int0"
+	2			"int0", "pps"
+	3			"int0", "int1", "int2"
+	4			"int0", "int1", "int2", "pps"
+  The order may be changed as long as they correspond to the interrupts
+  property. Currently, only i.mx7 uses "int1" and "int2". They correspond to
+  tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts.
+  For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse
+  per second interrupt associated with 1588 precision time protocol(PTP).
+
+Optional subnodes:
+- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
+  according to phy.txt in the same directory
+
+Deprecated optional properties:
+	To avoid these, create a phy node according to phy.txt in the same
+	directory, and point the fec's "phy-handle" property to it. Then use
+	the phy's reset binding, again described by phy.txt.
+- phy-reset-gpios : Should specify the gpio for phy reset
+- phy-reset-duration : Reset duration in milliseconds.  Should present
+  only if property "phy-reset-gpios" is available.  Missing the property
+  will have the duration be 1 millisecond.  Numbers greater than 1000 are
+  invalid and 1 millisecond will be used instead.
+- phy-reset-active-high : If present then the reset sequence using the GPIO
+  specified in the "phy-reset-gpios" property is reversed (H=reset state,
+  L=operation state).
+- phy-reset-post-delay : Post reset delay in milliseconds. If present then
+  a delay of phy-reset-post-delay milliseconds will be observed after the
+  phy-reset-gpios has been toggled. Can be omitted thus no delay is
+  observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.
+
+Example:
+
+ethernet@83fec000 {
+	compatible = "fsl,imx51-fec", "fsl,imx27-fec";
+	reg = <0x83fec000 0x4000>;
+	interrupts = <87>;
+	phy-mode = "mii";
+	phy-reset-gpios = <&gpio2 14 GPIO_ACTIVE_LOW>; /* GPIO2_14 */
+	local-mac-address = [00 04 9F 01 1B B9];
+	phy-supply = <&reg_fec_supply>;
+};
+
+Example with phy specified:
+
+ethernet@83fec000 {
+	compatible = "fsl,imx51-fec", "fsl,imx27-fec";
+	reg = <0x83fec000 0x4000>;
+	interrupts = <87>;
+	phy-mode = "mii";
+	phy-reset-gpios = <&gpio2 14 GPIO_ACTIVE_LOW>; /* GPIO2_14 */
+	local-mac-address = [00 04 9F 01 1B B9];
+	phy-supply = <&reg_fec_supply>;
+	phy-handle = <&ethphy>;
+	mdio {
+	        clock-frequency = <5000000>;
+		ethphy: ethernet-phy@6 {
+			compatible = "ethernet-phy-ieee802.3-c22";
+			reg = <6>;
+			max-speed = <100>;
+		};
+	};
+};
