You've alse removed the phy reset gpio on the Starlight board:

  snps,reset-gpios = <&gpio 63 GPIO_ACTIVE_LOW>

Why?

I missed this in v1 as the gmac handling was done exclusively in
jh7100-common. Thanks for noticing!

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.
