This patch adds fix_mac_speed() support for Altera socfpga Ethernet controller. Emac splitter is a soft IP core in FPGA system that converts GMII interface from Synopsys mac to RGMII/SGMII interface. This splitter core is an optional IP if user would like to use RGMII/SGMII interface in their system. Software needs to update a register in splitter core when there is speed change.

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.
|
|
|
|
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";
|
|
};
