+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.
+
+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>;
+ clocks-names = "stmmaceth";
+};
