To address the ABI compatibility issue between the kernel and DTS caused by

phy-mode.
Are you saying every other board DT got this correct? How do you know
that? Was this SoC never shipped to anybody, so the only possible
board is the QCOM RDK which never left the lab?
I doubt this is true, so you are probably breaking out of tree
boards. We care less about out of tree boards, but we also don't
needlessly break them.
You're right. My conclusion was based solely on browsing all RGMII-type
Qualcomm boards under the source tree, and I didn't take the scenario
you mentioned into account. I will work on coming up with a new
solution. If you have any suggestions, I will gladly take them as a
reference.
