+STMicroelectronics STM32 / MCU DWMAC glue layer controller
+
+This file documents platform glue layer for stmmac.
+Please see stmmac.txt for the other unchanged properties.
+
+The device node has following properties.
+
+Required properties:
+- compatible:  Should be "st,stm32-dwmac" to select glue, and
+	       "snps,dwmac-3.50a" to select IP vesrion.
+- clocks: Should contain the GMAC main clock, and tx clock
+- compatible:  Should be "st,stm32-dwmac" to select glue and
+	       "snps,dwmac-3.50a" to select IP version.
+- clocks: Should contain the MAC main clock
+- clock-names: Should contain the clock names "stmmaceth".
+- st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
+	      encompases the glue register, and the offset of the control register.
+
+Optional properties:
+- clocks: Could contain:
+	- the tx clock,
+	- the rx clock
+- clock-names: Could contain the clock names "tx-clk", "rx-clk"
+
+Example:
+
+		ethernet0: dwmac@...28000 {
+			compatible = "st,stm32-dwmac", "snps,dwmac-3.50a";
+			status = "disabled";
+			reg = <0x40028000 0x8000>;
+			reg-names = "stmmaceth";
+			interrupts = <0 61 0>, <0 62 0>;
+			interrupt-names = "macirq", "eth_wake_irq";
+			clock-names = "stmmaceth", "tx-clk", "rx-clk";
+			clocks = <&rcc 0 25>, <&rcc 0 26>, <&rcc 0 27>;
+			st,syscon = <&syscfg 0x4>;
+			snps,pbl = <8>;
+			snps,mixed-burst;
+			dma-ranges;
+		};
