According to:
stmmac_platform.c: stmmac_probe_config_dt
stmmac_main.c: stmmac_dvr_probe

dwmac controller may require one (stmmaceth) or two (stmmaceth+ahb)
reset signals, and the maxItems of resets/reset-names is going to be 2.

The gmac of Starfive Jh7110 SOC must have two resets.
it uses snps,dwmac-5.20 IP.

How do you test the bindings on hardware?

Thanks a lot.

Sorry, my fault. Tomaso tested gmac based on v5 version. I should only add Tested-by to the driver and dts patches, but not to dt-bindings.
I will fix it in the next version.

Best regards,
Samin
