1	* STMicroelectronics 10/100/1000 Ethernet driver (GMAC)
2	
3	Required 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.
30	
31	Optional properties:
32	- mac-address: 6 bytes, mac address
33	
34	Examples:
35	
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";
44		};
