+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: Must contain an entry for each entry in clock-names.
+- clock-names: Should be "stmmaceth" for the host clock.
+ Should be "tx-clk" for the MAC TX clock.
+ Should be "rx-clk" for the MAC RX clock.
+- 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.
+Example:
+
+ ethernet0: dwmac@40028000 {
+ 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;
+ };
