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.
