1Altera SOCFPGA SoC DWMAC controller 2 3This is a variant of the dwmac/stmmac driver an inherits all descriptions 4present in Documentation/devicetree/bindings/net/stmmac.txt. 5 6The device node has additional properties: 7 8Required 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 17Optional properties: 18altr,emac-splitter: Should be the phandle to the emac splitter soft IP node if 19 DWMAC controller is connected emac splitter. 20 21Example: 22 23gmac0: 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"; 33}; 34
