+Altera SOCFPGA SoC DWMAC controller
+
+This is a variant of the dwmac/stmmac driver an inherits all descriptions
+present in Documentation/devicetree/bindings/net/stmmac.txt.
+
+The device node has additional properties:
+
+Required properties:
+ - compatible  : Should contain "altr,socfpga-stmmac" along with
+                 "snps,dwmac" and any applicable more detailed
+                 designware version numbers documented in stmmac.txt
+ - altr,sysmgr-syscon : Should be the phandle to the system manager node that
+   encompasses the glue register, the register offset, and the register shift.
+
+Optional properties:
+altr,emac-splitter: Should be the phandle to the emac splitter soft IP node if
+               DWMAC controller is connected emac splitter.
+
+Example:
+
+gmac0: ethernet@ff700000 {
+       compatible = "altr,socfpga-stmmac", "snps,dwmac-3.70a", "snps,dwmac";
+       altr,sysmgr-syscon = <&sysmgr 0x60 0>;
+       status = "disabled";
+       reg = <0xff700000 0x2000>;
+       interrupts = <0 115 4>;
+       interrupt-names = "macirq";
+       mac-address = [00 00 00 00 00 00];/* Filled in by U-Boot */
+       clocks = <&emac_0_clk>;
+       clock-names = "stmmaceth";
+};
