* NXP LPC32xx SoC Ethernet Controller

Required properties:
- compatible: Should be "nxp,lpc-eth"
- reg: Address and length of the register set for the device
- interrupts: Should contain ethernet controller interrupt

Optional properties:
- phy-mode: String, operation mode of the PHY interface.
  Supported values are: "mii", "rmii" (default)
- use-iram: Use LPC32xx internal SRAM (IRAM) for DMA buffering
- local-mac-address : 6 bytes, mac address

Example:

	mac: ethernet@31060000 {
		compatible = "nxp,lpc-eth";
		reg = <0x31060000 0x1000>;
		interrupt-parent = <&mic>;
		interrupts = <29 0>;

		phy-mode = "rmii";
		use-iram;
	};
