Hi Emil,
I think the reset doesn't actually trigger because "snps,reset-gpios" is not a valid property, it should have been "snps,reset-gpio" (without the trailing "s").
However, this seems to be deprecated now, and the recommended approach would be to define the reset gpio in the phy node, which I did in [1].
Hopefully this won't cause any unexpected behaviour. Otherwise we should probably simply drop it.
