That looks odd. Where are the RGMII delays coming from? Normally its
"rgmii-id", which asks the PHY to insert the delays.

I don't see how did you resolve checkpatch warning.

Again: drop, not needed. You ignored my comment. Use stdout path.

This is a friendly reminder during the review process.

It seems my or other reviewer's previous comments were not fully
addressed. Maybe the feedback got lost between the quotes, maybe you
just forgot to apply it. Please go back to the previous discussion and
either implement all requested changes or keep discussing them.

Thank you.


Best regards,
Krzysztof
