Altera SOCFPGA SoC DWMAC controller
|
|
|
|
|
|
|
|
This is a variant of the dwmac/stmmac driver an inherits all descriptions
|
|
|
|
present in Documentation/devicetree/bindings/net/stmmac.txt.
|
|
|
|
|
|
|
|
The device node has additional properties:
|
|
|
|
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should contain "altr,socfpga-stmmac" along with
|
|
|
|
"snps,dwmac" and any applicable more detailed
|
|
|
|
designware version numbers documented in stmmac.txt
|
|
|
|
- altr,sysmgr-syscon : Should be the phandle to the system manager node that
|
|
|
|
encompasses the glue register, the register offset, and the register shift.
|

|
|
|
- altr,f2h_ptp_ref_clk use f2h_ptp_ref_clk instead of default eosc1 clock
|
|
|
|
for ptp ref clk. This affects all emacs as the clock is common.

|
|
|
Optional properties:
|
|
|
|
altr,emac-splitter: Should be the phandle to the emac splitter soft IP node if
|
|
|
|
DWMAC controller is connected emac splitter.
|

|
|
|
phy-mode: The phy mode the ethernet operates in
|
|
|
|
altr,sgmii-to-sgmii-converter: phandle to the TSE SGMII converter
|
|
|
|
|
|
|
|
This device node has additional phandle dependency, the sgmii converter:
|
|
|
|
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be altr,gmii-to-sgmii-2.0
|
|
|
|
- reg-names : Should be "eth_tse_control_port"
