The challenge with splitting this series lies in the fact that it 
attempts to reverse the incorrect semantics of phy-mode in both the 
driver code and the device tree. Selecting only part of the series would 
break Ethernet functionality on both boards.

As you can see, I’ve CC’d noautosel to prevent this issue. Given the 
circumstances, I’m wondering if it would be acceptable to leave the 
series as-is?
