Sorry for being late here. I've tested that removing the mdio and phy nodes on
the the Starlight board works fine, but the rx-internal-delay-ps = <900>
property not needed on any of my VisionFive V1 boards either. So I wonder why
you need that on your board

Also in the driver patch you add support for phy-mode = "rgmii-txid", but here
you still set it to "rgmii-id", so which is it?

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

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

Why?

Lastly the phy-mode and status are the same for the VF1 and Starlight boards,
so why can't these be set in the jh7100-common.dtsi?
