Hi, this controller is used in RiscV SoC from StarFive known as JH7110. Its TRM is available at https://doc-en.rvspace.org/JH7110/TRM/. I don't know if it contains anything you did not see yet, though. > Some specific questions: > * The existing code supports Synopsys versions 0x51 and 0x52.

From dmesg on my Star64 board: eqos0: <DesignWare EQOS Gigabit Ethernet for JH7110> mem 0x16030000-0x1603ffff irq 50,51,52 on simplebus0 eqos0: DesignWare EQOS ver 0x52 (0x41) eqos0: hw features 1a2173f7 09845904 01000000 00000000 I think it is what you are after.
