   1 Altera SOCFPGA SoC DWMAC controller
   2
   3 This is a variant of the dwmac/stmmac driver an inherits all descriptions
   4 present in Documentation/devicetree/bindings/net/stmmac.txt.

   6 The device node has additional properties:
   7
   8 Required properties:
   9  - compatible   : Should contain "altr,socfpga-stmmac" along with
  10                   "snps,dwmac" and any applicable more detailed
  11                   designware version numbers documented in stmmac.txt
  12  - altr,sysmgr-syscon : Should be the phandle to the system manager node that
  13    encompasses the glue register, the register offset, and the register shift.
  14  - altr,f2h_ptp_ref_clk use f2h_ptp_ref_clk instead of default eosc1 clock
  15    for ptp ref clk. This affects all emacs as the clock is common.
  16
  17 Optional properties:
  18 altr,emac-splitter: Should be the phandle to the emac splitter soft IP node if
  19                 DWMAC controller is connected emac splitter.

  21 Example:

  23 gmac0: ethernet@ff700000 {
  24         compatible = "altr,socfpga-stmmac", "snps,dwmac-3.70a", "snps,dwmac";
  25         altr,sysmgr-syscon = <&sysmgr 0x60 0>;
  26         status = "disabled";
  27         reg = <0xff700000 0x2000>;
  28         interrupts = <0 115 4>;
  29         interrupt-names = "macirq";
  30         mac-address = [00 00 00 00 00 00];/* Filled in by U-Boot */
  31         clocks = <&emac_0_clk>;
  32         clock-names = "stmmaceth";
