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";

};
