 3This file documents platform glue layer for stmmac.
 4Please see stmmac.txt for the other unchanged properties.

 6The device node has following properties.
 7
 8Required properties:
 9- compatible:  Should be "st,stm32-dwmac" to select glue, and
10	       "snps,dwmac-3.50a" to select IP version.
11- clocks: Must contain a phandle for each entry in clock-names.
12- clock-names: Should be "stmmaceth" for the host clock.
13	       Should be "mac-clk-tx" for the MAC TX clock.
14	       Should be "mac-clk-rx" for the MAC RX clock.
15- st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
16	      encompases the glue register, and the offset of the control register.
17Example:

19	ethernet@40028000 {
20		compatible = "st,stm32-dwmac", "snps,dwmac-3.50a";
21		status = "disabled";
22		reg = <0x40028000 0x8000>;
23		reg-names = "stmmaceth";
24		interrupts = <0 61 0>, <0 62 0>;
25		interrupt-names = "macirq", "eth_wake_irq";
26		clock-names = "stmmaceth", "mac-clk-tx", "mac-clk-rx";
27		clocks = <&rcc 0 25>, <&rcc 0 26>, <&rcc 0 27>;
28		st,syscon = <&syscfg 0x4>;
29		snps,pbl = <8>;
30		snps,mixed-burst;
31		dma-ranges;
