The device node has additional properties:
Required properties:
- - compatible : Should contain "altr,socfpga-stmmac" along with
- "snps,dwmac" and any applicable more detailed
+ - 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.
