+Nuvoton NPCM7XX 10/100 Ethernet MAC Controller (EMC)
+
+The NPCM7XX provides one or two Ethernet MAC RMII Controllers
+for WAN/LAN applications
+
+Required properties:
+- device_type     : Should be "network"
+- compatible      : "nuvoton,npcm750-emc" for Poleg NPCM7XX.
+- reg             : Offset and length of the register set for the device.
+- interrupts      : Contain the emc interrupts with flags for falling edge.
+                    first interrupt dedicated to Txirq
+                    second interrupt dedicated to Rxirq
+- phy-mode        : Should be "rmii" (see ethernet.txt in the same directory)
+- clocks          : phandle of emc reference clock.
+- resets          : phandle to the reset control for this device.
+- use-ncsi        : Use the NC-SI stack instead of an MDIO PHY
+
+Example:
+
+emc0: eth@f0825000 {
+	device_type = "network";
+	compatible = "nuvoton,npcm750-emc";
+	reg = <0xf0825000 0x1000>;
+	interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>,
+	             <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;
+	phy-mode = "rmii";
+	clocks = <&clk NPCM7XX_CLK_AHB>;
+
+	#use-ncsi; /* add this to support ncsi */
+
+	clock-names = "clk_emc";
+	resets = <&rstc 6>;
+	pinctrl-names = "default";
+	pinctrl-0 = <&r1_pins
+	             &r1err_pins
+	             &r1md_pins>;
+	status = "okay";
+};
