+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:
+
