Could you please move this one upper to have all the entries in the gpio
container alphanumerically sorted?

Same here.

There are some questions around this node from Andrew in v1 of this series,
which I don't see an answer for in any of the following versions. Could you
please clarify?
The rest looks good to me.
Thank you,

Sure, I will make sure that pin nodes are alphabetical (I found some
more that are not) in v5.

Sure, as for the RGMII I switched to rgmii-id so the PHY is adding the delays.
Though, I am not sure if its better to add them via MAC as it can add
the delays instead of the PHY,
so I am open to suggestions here.
As for the phys property, yes that is not required here as RGMII ports
are dedicated, there are no
SERDES lanes being used for them.
I have updated the bindings to account for this and it will be part of v5.
