Provides an options to use the ptp clock routed from the Altera FPGA fabric. Instead of the defalt eosc1 clock connected to the ARM HPS core. This setting affects all emacs in the core as the ptp clock is common.

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.
|
|
|
|
Example:
|
|
|
|
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";
|
|
};
