+Altera SOCFPGA SoC DWMAC controller
+
+The device node has following properties.
+
+Required properties:
+ - compatible : Should contain "altr,socfpga-stmmac"
+ - altr,sysmgr-syscon : Should be the phandle to the system manager node that
+ encompasses the glue register, and the register offset.
+
+Sub-nodes:
+The dwmac core should be added as subnode to SOCFPGA dwmac glue.
+- dwmac : The binding details of dwmac can be found in
+ Documentation/devicetree/bindings/net/stmmac.txt
+
+Example:
