Roland Stigge 4de02e4a28 net: Add device tree support to LPC32xx
This patch adds device tree support for lpc_eth.c.

The runtime option for MII/RMII is solved via the "phy-mode" property, SRAM
("IRAM") usage for DMA can be chosen via "use-iram".

* 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;
};
