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"
|
|
|
|
Example:
|
|
|
|
gmii_to_sgmii_converter: phy@0x100000240 {
|
|
compatible = "altr,gmii-to-sgmii-2.0";
|
|
reg = <0x00000001 0x00000240 0x00000008>,
|
|
<0x00000001 0x00000200 0x00000040>;
|
|
reg-names = "eth_tse_control_port";
|
|
clocks = <&sgmii_1_clk_0 &emac1 1 &sgmii_clk_125 &sgmii_clk_125>;
|
|
clock-names = "tse_pcs_ref_clk_clock_connection", "tse_rx_cdr_refclk";
|
|
};
|
|
|
|
gmac0: ethernet@ff700000 {
|
|
compatible = "altr,socfpga-stmmac", "snps,dwmac-3.70a", "snps,dwmac";
|
|
altr,sysmgr-syscon = <&sysmgr 0x60 0>;
|
|
status = "disabled";
|
|
reg = <0xff700000 0x2000>;
|
|
interrupts = <0 115 4>;
|
|
interrupt-names = "macirq";
|
|
mac-address = [00 00 00 00 00 00];/* Filled in by U-Boot */
|
|
clocks = <&emac_0_clk>;
|
|
clock-names = "stmmaceth";
|
|
phy-mode = "sgmii";
|
|
altr,gmii-to-sgmii-converter = <&gmii_to_sgmii_converter>;
