Hi Stephen,

The kernel's bindings/net/snps,dwmac.yaml does not mention any reset-gpios property (which is what the existing code parses just above the portion that is quoted by this patch as context). I suspect that this patch should simply change the name of the property that this function parses to align with the binding, and fix any DTs in U-Boot that also don't match the binding?
The kernel's ./Documentation/devicetree/bindings/net/stmmac.txt mentions that Required properties:
- phy-mode: See ethernet.txt file in the same directory. - snps,reset-gpio gpio number for phy reset. - snps,reset-active-low boolean flag to indicate if phy reset is active low. - snps,reset-delays-us is triplet of delays The 1st cell is reset pre-delay in micro seconds. The 2nd cell is reset pulse in micro seconds. The 3rd cell is reset post-delay in micro seconds.
