+Hisilicon Fast Ethernet MAC controller
+
+Required properties:
+- compatible: should contain one of the following version strings:
+	* "hisilicon,hisi-femac-v1"
+	* "hisilicon,hisi-femac-v2"
+	and the soc string "hisilicon,hi3516cv300-femac".
+- reg: specifies base physical address(s) and size of the device registers.
+  The first region is the MAC core register base and size.
+  The second region is the global MAC control register.
+- interrupts: should contain the MAC interrupt.
+- clocks: A phandle to the MAC main clock.
+- resets: should contain the phandle to the MAC reset signal(required) and
+	the PHY reset signal(optional).
+- reset-names: should contain the reset signal name "mac"(required)
+	and "phy"(optional).
+- phy-mode: see ethernet.txt [1].
+- phy-handle: see ethernet.txt [1].
+- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
+	The 1st cell is reset pre-delay in micro seconds.
+	The 2nd cell is reset pulse in micro seconds.
+	The 3rd cell is reset post-delay in micro seconds.
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt[1].

+Example:
+	hisi_femac: ethernet@10090000 {
+		compatible = "hisilicon,hi3516cv300-femac","hisilicon,hisi-femac-v2";
+		reg = <0x10090000 0x1000>,<0x10091300 0x200>;
+		interrupts = <12>;
+		clocks = <&crg HI3518EV200_ETH_CLK>;
+		resets = <&crg 0xec 0>,<&crg 0xec 3>;
+		reset-names = "mac","phy";
+		mac-address = [00 00 00 00 00 00];
+		phy-mode = "mii";
+		phy-handle = <&phy0>;
+		hisilicon,phy-reset-delays-us = <10000 20000 20000>;
+	};
