1* STMicroelectronics 10/100/1000 Ethernet driver (GMAC)

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: 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.

29Optional 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".
