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.
