dts: socfpga: Add DTS entry for adding the stmmac glue layer for stmmac. 



This patch adds the dts bindings documenation for the Altera SOCFPGA glue
layer for the Synopsys STMMAC ethernet driver.

Signed-off-by: default avatarDinh Nguyen <dinguyen@altera.com>
Acked-by: default avatarDavid S. Miller <davem@davemloft.net>
---
v3: Remove stray empty line at end of socfpga_cyclone5_socdk.dts
v2: Use the dwmac-sti as an example for a glue layer and split patch up
to have dts as a separate patch. Also cc dts maintainers since there is
a new binding.

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:



ethernet0: ethernet0 {

	#address-cells = <1>;

	#size-cells = <1>;



	compatible = "altr,socfpga-stmmac";

	altr,sysmgr-syscon = <&sysmgr 0x60>;

	status = "disabled";

	ranges;



	gmac0: gmac0@ff700000 {

		compatible = "snps,dwmac-3.70a", "snps,dwmac";

		reg = <0xff700000 0x2000>;

		interrupts = <0 115 4>;

		interrupt-names = "macirq";

		mac-address = [00 00 00 00 00 00];/* Filled in by U-Boot */

		clocks = <&emac0_clk>;

		clock-names = "stmmaceth";

	};
