   2
   3Required properties:
   4- compatible: Should be "nxp,lpc-eth"
   5- reg: Address and length of the register set for the device
   6- interrupts: Should contain ethernet controller interrupt
   7
   8Optional properties:
   9- phy-mode: String, operation mode of the PHY interface.
  10  Supported values are: "mii", "rmii" (default)
  11- use-iram: Use LPC32xx internal SRAM (IRAM) for DMA buffering
  12- local-mac-address : 6 bytes, mac address

  14Example:
  15
  16        mac: ethernet@31060000 {
  17                compatible = "nxp,lpc-eth";
  18                reg = <0x31060000 0x1000>;
  19                interrupt-parent = <&mic>;
  20                interrupts = <29 0>;
  21
  22                phy-mode = "rmii";
  23                use-iram;
  24        };
