This patch series adds support for configuring RGMII internal delays for the

So i think you are doing things in the wrong order. You first need to
sort out the mess of most, if not all, AST2600 have the wrong
phy-mode, because the RGMII delay configuration is hidden, and set
wrongly.

Please fix that first.

Then consider how you can add fine tuning of the delays. Maybe that
needs to wait for AST2700.
