Hi Andrew,

Thank you for your reply.

Add the new property, "aspeed,rgmii-delay-ps", to specify per step of
RGMII delay in different MACs. And for Aspeed platform, the total
steps of RGMII delay configuraion is 32 steps, so the total delay is
"apseed,rgmii-delay-ps' * 32.

You already have hard coded base addresses to identify the MAC instances. So i
don't see the need for this in DT. Just extend the switch statement with the
delay step.

Agreed.
Indeed, no additional property is needed to specify this.
I will remove this property in next version.

Thanks,
Jacky
