+Nuvoton NPCM7XX 10/100 Ethernet MAC Controller (EMC)
+
+The NPCM750x provides two identical Ethernet MAC Controllers
+for WAN/LAN applications
+
+Required properties:
+- device_type : Should be "network"
+- compatible : "nuvoton,npcm750-emc" for Poleg NPCM750.
+- 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.
+- use-ncsi : Use the NC-SI stack instead of an MDIO PHY
+
+Example:
+
+emc0: eth at 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";
+ pinctrl-names = "default";
+ pinctrl-0 = <&r1_pins
+ &r1err_pins
+ &r1md_pins>;
+ status = "okay";
+};
