1* STMicroelectronics 10/100/1000 Ethernet driver (GMAC)
2
3Required properties:
4- compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac"
5	For backwards compatibility: "st,spear600-gmac" is also supported.
6- reg: Address and length of the register set for the device
7- interrupt-parent: Should be the phandle for the interrupt controller
8  that services interrupts for this device
9- interrupts: Should contain the STMMAC interrupts
10- interrupt-names: Should contain the interrupt names "macirq"
11  "eth_wake_irq" if this interrupt is supported in the "interrupts"
12  property
13- phy-mode: String, operation mode of the PHY interface.
14  Supported values are: "mii", "rmii", "gmii", "rgmii".
15- snps,phy-addr		phy address to connect to.
16- snps,reset-gpio 	gpio number for phy reset.
17- snps,reset-active-low boolean flag to indicate if phy reset is active low.
18- snps,reset-delays-us  is triplet of delays
19	The 1st cell is reset pre-delay in micro seconds.
20	The 2nd cell is reset pulse in micro seconds.
21	The 3rd cell is reset post-delay in micro seconds.
22- snps,pbl		Programmable Burst Length
23- snps,fixed-burst	Program the DMA to use the fixed burst mode
24- snps,mixed-burst	Program the DMA to use the mixed burst mode
25- snps,force_thresh_dma_mode	Force DMA to use the threshold mode for
26				both tx and rx
27- snps,force_sf_dma_mode	Force DMA to use the Store and Forward
28				mode for both tx and rx. This flag is
29				ignored if force_thresh_dma_mode is set.

31Optional properties:
32- mac-address: 6 bytes, mac address

34Examples:

36	gmac0: ethernet@e0800000 {
37		compatible = "st,spear600-gmac";
38		reg = <0xe0800000 0x8000>;
39		interrupt-parent = <&vic1>;
40		interrupts = <24 23>;
41		interrupt-names = "macirq", "eth_wake_irq";
42		mac-address = [000000000000]; /* Filled in by U-Boot */
43		phy-mode = "gmii";
