-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 : For Cyclone5/Arria5 SoCs it should contain
- "altr,socfpga-stmmac". For Arria10/Agilex/Stratix10 SoCs
- "altr,socfpga-stmmac-a10-s10".
- 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.
- On Cyclone5/Arria5, the register shift represents the PHY mode bits, while
- on the Arria10/Stratix10/Agilex platforms, the register shift represents
- bit for each emac to enable/disable signals from the FPGA fabric to the
- EMAC modules.
- - 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"
-
-Example:
-
-gmii_to_sgmii_converter: phy@100000240 {
- compatible = "altr,gmii-to-sgmii-2.0";
- reg = <0x00000001 0x00000240 0x00000008>,

-};

Changes to the binding while converting: - add "snps,dwmac-3.7{0,2,4}a". They are used, but undocumented. - altr,f2h_ptp_ref_clk is not a required property but optional.
