There are four MACs in the AST2600. In the DT bindings and DTS
files, what would be the recommended way to identify which MAC is

which?

In version 3 of my patches, I used the aliases in the DTSI file to
allow the driver to get the MAC index.

It is a bit ugly, but you are working around broken behaviour, so
sometimes you need to accept ugly. The addresses are fixed. You know
1e660000 is mac0, 1e680000 is mac1, etc. Put the addresses into the
driver, for compatible aspeed,ast2600-mac.

I used this fixed address as MAC index in the first version of this series.
But the other reviewer mentioned maybe there has the other better way
to identify index.

I find the "aliase", on preparing the v2 and v3, I think it may be a
way to do that. But I am not sure.
So, I would like to confirm the other good way before submitting the
next version.

The problem with alias is that it normally a board property, in the .dts file. A
board might want a different mapping, which could then break delays.

Agreed. I looked through ethernet-controller.yaml, but it doesn't seem to have 
any property that fits our needs.
I will use the fixed-address value from the reg property to identify the index of 
MACs to configure the RGMII delay in next version.
