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: See ethernet.txt file in the same directory.
14	- snps,reset-gpio 	gpio number for phy reset.
15	- snps,reset-active-low boolean flag to indicate if phy reset is active low.
16	- snps,reset-delays-us  is triplet of delays
17		The 1st cell is reset pre-delay in micro seconds.
18		The 2nd cell is reset pulse in micro seconds.
19		The 3rd cell is reset post-delay in micro seconds.
20	- snps,pbl		Programmable Burst Length
21	- snps,fixed-burst	Program the DMA to use the fixed burst mode
22	- snps,mixed-burst	Program the DMA to use the mixed burst mode
23	- snps,force_thresh_dma_mode	Force DMA to use the threshold mode for
24					both tx and rx
25	- snps,force_sf_dma_mode	Force DMA to use the Store and Forward
26					mode for both tx and rx. This flag is
27					ignored if force_thresh_dma_mode is set.
28	
29	Optional properties:
30	- resets: Should contain a phandle to the STMMAC reset signal, if any
31	- reset-names: Should contain the reset signal name "stmmaceth", if a
32		reset phandle is given
33	- max-frame-size: See ethernet.txt file in the same directory
34	- clocks: If present, the first clock should be the GMAC main clock,
35	  further clocks may be specified in derived bindings.
36	- clock-names: One name for each entry in the clocks property, the
37	  first one should be "stmmaceth".
38	
39	Examples:
40	
41		gmac0: ethernet@e0800000 {
42			compatible = "st,spear600-gmac";
43			reg = <0xe0800000 0x8000>;
44			interrupt-parent = <&vic1>;
45			interrupts = <24 23>;
46			interrupt-names = "macirq", "eth_wake_irq";
47			mac-address = [000000000000]; /* Filled in by U-Boot */
48			max-frame-size = <3800>;
49			phy-mode = "gmii";
50			clocks = <&clock>;
51			clock-names = "stmmaceth">;
52		};
