   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.
   5
   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.
  20 phy-mode: The phy mode the ethernet operates in
  21 altr,sgmii-to-sgmii-converter: phandle to the TSE SGMII converter
  22
  23 This device node has additional phandle dependency, the sgmii converter:
  24
  25 Required properties:
  26  - compatible   : Should be altr,gmii-to-sgmii-2.0
  27  - reg-names    : Should be "eth_tse_control_port"
  28
  29 Example:
