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: 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- snps,multicast-filter-bins:	Number of multicast filter hash bins
29				supported by this device instance
30- snps,perfect-filter-entries:	Number of perfect filter entries supported
31				by this device instance
32
33Optional properties:
34- resets: Should contain a phandle to the STMMAC reset signal, if any
35- reset-names: Should contain the reset signal name "stmmaceth", if a
36	reset phandle is given
37- max-frame-size: See ethernet.txt file in the same directory
38- clocks: If present, the first clock should be the GMAC main clock,
39  further clocks may be specified in derived bindings.
40- clock-names: One name for each entry in the clocks property, the
41  first one should be "stmmaceth".
42- clk_ptp_ref: this is the PTP reference clock; in case of the PTP is
43  available this clock is used for programming the Timestamp Addend Register.
44  If not passed then the system clock will be used and this is fine on some
45  platforms.
