-Davicom DM9000 Fast Ethernet controller
-
-Required properties:
-- compatible = "davicom,dm9000";
-- reg : physical addresses and sizes of registers, must contain 2 entries:
-    first entry : address register,
-    second entry : data register.
-- interrupts : interrupt specifier specific to interrupt controller
-
-Optional properties:
-- davicom,no-eeprom : Configuration EEPROM is not available
-- davicom,ext-phy : Use external PHY
-- reset-gpios : phandle of gpio that will be used to reset chip during probe
-- vcc-supply : phandle of regulator that will be used to enable power to chip
-
-Example:
-
-	ethernet@18000000 {
-		compatible = "davicom,dm9000";
-		reg = <0x18000000 0x2 0x18000004 0x2>;
-		interrupt-parent = <&gpn>;
-		interrupts = <7 4>;
-		local-mac-address = [00 00 de ad be ef];
-		davicom,no-eeprom;
-		reset-gpios = <&gpf 12 GPIO_ACTIVE_LOW>;
-		vcc-supply = <&eth0_power>;
-	};
