Thanks for including the 6320 model!

Yes, that was the reason for the register read failure.

Initially, I had described the reset GPIO inside using reset-gpios inside
the switch node, just like described in the Linux binding document:
Documentation/devicetree/bindings/net/dsa/marvell.txt

It did not work, so I moved it to phy-reset-gpios inside the fec node.

I don't think this is a blocker for your v5 series. We can improve it
later so that
the binding from Linux could also work in U-Boot.

Thanks
